Referring to fig. 1 and 2, a floor drain drainage structure 10 in an embodiment is used for being installed in an indoor place where drainage is needed, and has good drainage effect, continuous and effective deodorization and insect prevention, and anti-overflow function. Specifically, the floor drain drainage structure 10 includes a water inlet pipe 100 and a drainage body 200.
The drainage body 200 includes a water storage portion 210 and a drainage portion 220, the side wall of the water storage portion 210 encloses a water storage cavity 211, a fixing hole 212 is formed on the top wall of the water storage cavity 211, and one end of the water inlet pipe 100 is inserted into the fixing hole 212 and extends into the water storage cavity 211. The side wall of the drainage part 220 encloses a drainage cavity 221, the drainage cavity 221 is communicated with the water storage cavity 211, a water limiting part 230 is formed at the communication part of the drainage cavity 221 and the water storage cavity 211, the height of the water limiting part 230 is higher than the end face of one end of the water inlet pipe 100, a drainage outlet 222 is formed on the side wall of the drainage cavity 221, and the inner wall of the drainage cavity 221 is obliquely arranged along the gravity direction towards the direction close to the drainage outlet 222. The end surface of one end of the water inlet pipe 100 is a surface facing the bottom wall of the water storage cavity 211.
When the floor drain drainage structure 10 is in use, one end of the water inlet pipe 100 is inserted into the fixing hole 212 of the water storage portion 210 and further extends into the water storage cavity 211 of the water storage portion 210, so that the water inlet pipe 100 is communicated with the water storage cavity 211. The side wall of the drainage part 220 encloses a drainage cavity 221, and the drainage cavity 221 is communicated with the water storage cavity 211. Thus, sewage enters from the water inlet pipe 100 and flows into the water storage chamber 211. Since the water limiting portion 230 is formed at the communication portion of the water discharge chamber 221 and the water storage chamber 211, the height of the water limiting portion 230 is higher than the end surface of one end of the water inlet pipe 100. Therefore, when the water level in the water storage cavity 211 exceeds the end surface of one end of the water inlet pipe 100, odor, cockroaches and the like in the building water drainage vertical pipe can be prevented from entering the water inlet pipe 100 and then being transferred into a room, and an effective deodorizing and insect preventing effect is achieved. Further, when the water level in the water inlet pipe 100 is further raised, the water limit part 230 is raised, and the sewage in the water storage chamber 211 flows into the water discharge chamber 221 of the water discharge part 220 and is discharged through the water discharge port 222 on the side wall of the water discharge chamber 221. Meanwhile, the inner wall of the drainage cavity 221 is inclined along the gravity direction in the direction close to the drainage outlet 222, so that a natural downflow channel can be provided for the drainage of sewage, the drainage of sewage is facilitated, and the drainage effect can be improved.
Specifically, the inner wall of the drain chamber 221 is inclined at an angle of 2 ° to 5 ° with respect to the horizontal surface in a direction approaching the drain port 222. By having the inclination angle of the inner wall of the drainage cavity 221 with respect to the horizontal plane of 2 ° -5 °, it is possible to avoid increasing the height of the floor drain structure 10 due to an excessively large inclination angle, and at the same time to avoid having too small inclination angle, which cannot perform an effective diversion function. The structure not only facilitates the installation of the floor drain structure 10, but also plays a role in guiding the sewage discharge.
Specifically, in the present embodiment, the inner wall of the drain chamber 221 is inclined at an angle of 3 ° to the horizontal in a direction approaching the drain port 222. Of course, in other embodiments, the inclination angle of the inner wall of the drainage cavity 221 with respect to the horizontal plane may be determined according to the installation environment, as long as the drainage effect can be effectively achieved.
Optionally, the water outlet 222 is formed on a side wall of the water outlet 220 facing away from the water storage cavity 211, so that the water is effectively discharged after being guided by the water outlet cavity 221.
Specifically, the water reservoir 210 is disposed obliquely in the gravity direction toward the bottom wall of the water intake pipe 100 in the direction approaching the water outlet 222. When sewage enters the water storage cavity 211 from the water inlet pipe 100, the sewage can be guided to flow towards the water discharge cavity 221 by the inclined arrangement of the water storage part 210 towards the bottom wall of the water inlet pipe 100 along the gravity direction, so that the water discharge effect is further improved.
Optionally, a water pressing table 213 is formed on an inner wall of the water storage portion 210, and the water pressing table 213 is located on a top wall of the water storage portion 210, wherein the top wall of the water storage portion 210 is disposed opposite to a bottom wall of the water storage portion 210. The water pressing table 213 is disposed opposite to the water limiting portion 230 at a distance, and the surface of the water pressing table 213 facing the bottom wall of the water storage portion 210 is a water pressing surface 214. Wherein the water pressing surface 214 is level with the highest position of the water limiting part 230, or the water pressing surface 214 of the water pressing platform 213 is slightly lower than the highest position of the water limiting part 230.
In use, the sewage to be discharged enters the water storage cavity 211 from the water inlet pipe 100, so that the water level in the water storage cavity 211 is continuously close to the highest positions of the water pressing table 213 and the water limiting part 230. When the water level contacts the water pressing surface 214 of the pressing stage 213, as the water level in the water inlet pipe 100 continues to rise beyond the water limiting portion 230, the sewage can pass over the water limiting portion 230 and enter the water discharge chamber 221. Due to the inertia of the water flow, a negative pressure space is instantaneously formed between the water surface and the water pressure surface 214, and the negative pressure can form a siphon effect, so that the water discharge is further accelerated. Meanwhile, as the water level contacts with the water pressing surface 214 of the water pressing table 213, sewage can only flow out through the gap between the water pressing table 213 and the water limiting part 230, and thus air in the water storage cavity 211 can be effectively discharged. All or part of air can be further discharged from the drainage cavity 221 through water flow, so that air in the water storage cavity 211 and air in the drainage cavity 221 are reduced, air pressure in the drainage cavity 221 and air pressure in the water storage cavity 211 are reduced, negative pressure can be generated, a siphon effect is generated, the drainage speed is effectively accelerated, and the drainage efficiency is improved.
Alternatively, the water limiting part 230 is formed by bending the inner wall of the communication place of the drainage chamber 221 and the water storage chamber 211 inwards, so that the structure of the water limiting part 230 is simpler. Meanwhile, the water limiting part 230 is formed by inwards bending the inner wall of the communication part of the drainage cavity 221 and the water storage cavity 211, so that the water limiting part 230 and the inner walls of the drainage cavity 221 and the water storage cavity 211 are smoothly transited, sharp angles or sharp edges are avoided, the flow in the sewage discharge process is influenced, and the sewage discharge efficiency is further influenced. Of course, in other embodiments, the water limiting portion 230 may be a boss, which is disposed on an inner wall of the communicating portion between the water draining cavity 221 and the water storage cavity 211, so long as the flow of sewage can be limited to a certain extent, a water seal with a certain height is formed, and odor or cockroaches are prevented from entering the water inlet pipe 100 through the water storage cavity 211 and then being transferred into the room.
Optionally, the water pressing platform 213 is formed by bending the top wall of the water storage portion 210 into the water storage cavity 211, so that the structure of the water pressing platform 213 is simpler, the manufacturing process is simpler, the structure of the water pressing platform 213 is avoided being formed independently, and the manufacturing cost is increased. Of course, in other embodiments, the water pressing stage 213 may also be a plate-like structure provided on the inner side of the top wall of the water storage chamber 211.
Specifically, the water pressing surface 214 of the water pressing platform 213 is a plane, so that the water level surface can be effectively contacted with the water pressing surface 214, and due to the inertia of water flow, a negative pressure space can be instantaneously formed between the liquid level and the water pressing surface 214 after water in the water storage cavity 211 flows out, so as to generate a siphon effect.
In this embodiment, the drainage portion 220 and the water storage portion 210 are integrally formed, so that the structure of the drainage body 200 is simpler, the manufacturing process is simple, and the manufacturing cost is lower. Meanwhile, the drainage body 200 is more stable, and the phenomenon of water leakage in the drainage process is avoided. Specifically, the drain portion 220 and the water storage portion 210 are integrally formed as an injection-molded part, which can further reduce the manufacturing cost of the drain body 200.
Optionally, the drainage body 200 further includes a mounting table 240, where the mounting table 240 is disposed on the bottom wall of the water storage portion 210 and is located outside the water storage portion 210. The floor drain 10 can be conveniently installed on the ground by the mounting table 240. Specifically, the mounting table 240 is provided with mounting holes 241, and pipes with different heights can be mounted through the mounting holes 241 so as to adapt to different mounting heights, and further improve the mounting adaptability of the floor drain structure 10.
In this embodiment, the water storage portion 210 and the mounting table 240 are integrally formed, so that the manufacturing process of the mounting table 240 is simpler, and the cost of the drainage body 200 is effectively reduced. Of course, in other embodiments, the mounting table 240 may also be secured to the outer wall of the reservoir 210 by glue or fasteners.
Optionally, the drainage body 200 further includes a support table 250, the support table 250 is disposed on the bottom wall of the water storage cavity 211, and the water inlet pipe 100 abuts against a side of the support table 250 facing away from the bottom wall of the water storage cavity 211. The supporting table 250 can enable a space to be formed between the end face of one end of the water inlet pipe 100 and the bottom wall of the water storage cavity 211, and sewage in the water inlet pipe 100 can effectively enter the water storage cavity 211 through the space between the water inlet pipe 100 and the bottom wall of the water storage cavity 211.
In this embodiment, the diameter of the bottom wall of the water storage cavity 211 is 100mm-150mm. Avoiding the excessive size of the water storage chamber 211 and increasing the cost of the floor drain structure 10. Meanwhile, the phenomenon that the water storage cavity 211 is too small to cause the insufficient water sealing volume is avoided, so that the water in the water storage cavity 211 evaporates faster, and the water sealing fails is avoided. At the same time, the gap between the water inlet pipe 100 and the inner wall of the water storage cavity 211 is prevented from being too small, and the resistance of sewage in the discharging process is further prevented from being increased. Specifically, the diameter of the bottom wall of the water storage cavity 211 is preferably 115mm.
In particular, in the present embodiment, the space between the bottom wall of the water reservoir 210 and the end face of one end of the water inlet pipe 100 is 15mm to 30mm. Too small a space between the bottom wall of the water storage part 210 and the end surface of one end of the water inlet pipe 100 is unfavorable for sewage in the water inlet pipe 100 to enter the water storage cavity 211 and is easy to cause blockage; meanwhile, the space between the bottom wall of the water storage portion 210 and the end surface of one end of the water inlet pipe 100 is too large, which easily results in an increase in the overall height of the floor drain structure 10, thereby increasing the manufacturing cost.
Referring to fig. 3, optionally, the floor drain structure 10 further includes a fastener 300, the drain body 200 further includes a fixing portion 260, the fixing portion 260 is disposed on a top wall of the water storage portion 210, and the fixing hole 212 is formed on the fixing portion 260. The fastener 300 is provided on the fixing portion 260 to fix the water inlet pipe 100 to the fixing portion 260. By the cooperation of the fixing portion 260 and the fastening member 300, the water inlet pipe 100 can be effectively fixed to the fixing portion 260 and thus to the water discharge body 200.
Specifically, the fastener 300 includes a sealing ring 310 and a fastening nut 320, the sealing ring 310 is sleeved on the water inlet pipe 100 and is located in the fixing hole 212, and the fastening nut 320 can be screwed on the fixing portion 260. The water inlet pipe 100 is effectively fastened on the fixing portion 260 through the fastening nut 320, and meanwhile, the water inlet pipe 100 can be detached relative to the fixing portion 260 due to the fact that the fastening nut 320 is connected to the fixing portion 260 through threads, and accordingly the water inlet pipe 100 is convenient to install, detach and replace. The sealing ring 310 can effectively seal the gap between the water inlet pipe 100 and the fixing portion 260, and prevent sewage from leaking out of the gap between the water inlet pipe 100 and the fixing portion 260.
Further, a clamping table 2121 is formed on an inner wall of the fixing hole 212, and the sealing ring 310 can be placed on the clamping table 2121. By arranging the clamping table 2121, the sealing ring 310 can be effectively arranged in the fixing hole 212, so that the sealing ring 310 is prevented from sliding in the fixing hole 212, and the sealing effect of the sealing ring 310 on the water inlet pipe 100 and the fixing portion 260 is prevented from being influenced.
Optionally, the fastener 300 further includes a pressing member 330, where the pressing member 330 can be sleeved on the water inlet pipe 100 and located in the fixing hole 212. While compression member 330 can be compressed against the side of seal 310 facing away from chuck 2121. The pressing piece 330 can further limit the movement of the sealing ring 310, so that the sealing ring 310 can be effectively arranged between the water inlet pipe 100 and the fixing portion 260, the stability of the arrangement of the sealing ring 310 is further improved, and the sealing stability of the water inlet pipe 100 and the fixing portion 260 is further improved.
The floor drain structure 10 further comprises a water outlet pipe 400, wherein the water outlet pipe 400 comprises a connecting part 410 and a water outlet part 420 connected with the connecting part 410, the height of the water outlet part 420 is lower than that of the connecting part 410, and the connecting part 410 is connected with the water outlet 222 of the water outlet part 220. The sewage can be discharged into the water outlet pipe 400 through the water discharge port 222, and since the height of the water outlet part 420 is lower than the connection part 410, the sewage can flow effectively and be further discharged through the water outlet part 420. A diversion channel is provided for the discharge of sewage through the water outlet pipe 400, so that the efficiency of sewage discharge is further improved.
Specifically, the inner diameter of the junction between the junction 410 and the water outlet 420 is smaller than the inner diameter of the junction 410 and the inner diameter of the water outlet 420. In the sewage draining process, since the inner diameter of the connection portion 410 and the water outlet portion 420 is smaller, the connection portion is easily filled with sewage when the sewage passes through the connection portion of the connection portion 410 and the water outlet portion 420, and then a closed air chamber is formed in the drainage chamber 221 and the water storage chamber 211. In the process that sewage is continuously discharged from the water outlet part 420 of the water outlet pipe 400, the volume of the air cavity is increased, so that the pressure of the air cavity is reduced, and then the sewage in the water inlet pipe 100 can be sucked into the water storage cavity 211, and the sewage in the water storage cavity 211 is sucked into the water outlet cavity 221, so that the siphon effect is further improved, the sewage is discharged from the water outlet pipe 400, and the discharge efficiency of the sewage is effectively accelerated. Meanwhile, due to the formation of the air cavity, the sewage in the water outlet pipe 400 can be effectively prevented from flowing back into the water draining cavity 221 or the water storing cavity 211, and further, the effect of effectively preventing overflow can be achieved.
In this embodiment, the inner diameter of the connection part 410 and the water outlet part 420 is 30mm-40mm, so that the influence on the drainage flow caused by too small connection part of the connection part 410 and the water outlet part 420 can be avoided; further, the connection part between the connection part 410 and the water outlet part 420 is prevented from being too large, so that the connection part between the connection part 410 and the water outlet part 420 cannot be effectively sealed in the sewage discharge process, and a sealed air cavity cannot be formed.
Specifically, the inner diameter of the junction 410 and the outlet 420 is 32mm. Of course, in other embodiments, the inner diameter of the junction 410 and the outlet 420 may be greater or less than 32mm.
In one embodiment, taking the diameter of the water storage cavity 211 as an example, the diameter of the water inlet pipe 100 is 50mm-80mm, and the diameter of the water outlet part 420 of the water outlet pipe 400 is 40mm-60mm. When the ratio of the diameter of the water inlet pipe 100 to the diameter of the water outlet portion 420 of the water outlet pipe 400 is about 1.5, the air in the water storage cavity 211 and the water outlet cavity 221 is easily discharged gradually during the discharging process, so that the siphon effect is more easily generated, and the water discharging efficiency is improved. In use, the larger the diameter of the water inlet pipe 100, the faster the water discharge, but the diameter of the water storage cavity 211 needs to be increased at the same time, which causes the volume of the floor drain water discharge structure 10 to be increased, and the cost to be increased. If the diameter of the water outlet portion 420 of the water outlet pipe 400 is increased, the air in the water outlet chamber 221 and the water storage chamber 211 is not easily discharged, so that the siphon effect is weak in the water discharging process. Meanwhile, an increase in the diameter of the outlet portion 420 of the outlet pipe 400 also results in an increase in the risk of backflow of sewage. Specifically, the diameter of the water inlet pipe 100 is preferably 75mm, and the diameter of the water outlet portion 420 of the water outlet pipe 400 is preferably 50mm.
The drainage amount of the floor drain drainage structure 10 in the embodiment is 30L/min-50L/min, the drainage amount is larger, and the drainage effect is better.
The above-described embodiments represent only a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
