Description

Easy-to-clean super-spin toilet bowl

Technical Field

The invention relates to the technical field of sanitary equipment, in particular to an easy-to-clean super-spin toilet bowl.

Background

As a product which needs to be used every day in daily life, the closestool becomes essential bathroom furniture in many families.

However, in the existing toilet flushing technology, a sealed flushing channel is arranged at the top end of the toilet seat; accordingly, a plurality of injection holes are provided at the top of the toilet seat flushing chamber to communicate with the flushing passage, so that water is sprayed at the top of the flushing chamber and a water vortex is formed, thereby flushing the entire flushing chamber.

The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to a number of technical features being indicated. Thus, features defined as "first", "second" and "third" may explicitly or implicitly include one or more of the features.

In a preferred embodiment of the present application, as shown in fig. 1 to 6, an easy-to-clean super-spin toilet includes a flush tank 1, a toilet seat 2, and a drain pipe 3; the flushing tank 1 is mounted on the top of the toilet seat 2; a water storage cavity 12 is arranged inside the flushing tank 1, and a drain valve mounting port 11 is arranged at the bottom of the water storage cavity 12; the interior of the toilet seat 2 is provided with a flushing cavity 21, a water sealing structure 26, a water drainage channel 22 and a vortex diversion trench 23; the water inlet end of the drainage channel 22 is communicated with the water storage cavity 12 through the drainage valve mounting port 11; the discharge channel 22 includes a flushing jet 221; the vortex guiding groove 23 is arranged at the top of the washing cavity 21; the cavity surface at the top of the washing cavity 21 is connected with the vortex diversion trench 23; the water discharge channel 22 is communicated with the vortex guide groove 23 through the washing jet port 221; the water sealing structure 26 is arranged at the bottom of the washing cavity 21, and the top of the water sealing structure 26 is communicated with the washing cavity 21; the bottom of the water sealing structure 26 is communicated with the sewage draining pipe 3.

In the embodiment, a water storage cavity 12 communicated with an external water source is arranged inside the flushing tank 1, and the water storage cavity 12 is used for storing water for flushing a toilet; and the drain valve mounting port 11 is used for mounting a drain valve, and the communication or the closing connection of the water storage cavity 12 and the main flow passage is controlled through the drain valve. When connected, water in the water storage chamber 12 flows from the drain valve mounting port 11 to the drain flush passage 22. When in the closed connection, water cannot flow into the drain flush passage 22 through the drain valve mounting port 11. After the water flows into the water discharge channel 22, the water is injected into the vortex guiding groove 23 through the flushing injection port 221. Further, in this embodiment, the vortex guiding groove 23 is circular, so that when the water flows on the vortex guiding groove 23, the shape of the water flow forms a spiral shape, and the water flow falls to the cavity surface of the washing cavity 21 under the action of gravity and becomes a water vortex, thereby washing the cavity surface of the washing cavity 21. It should be noted that the cavity surface of the flushing cavity 21 is inclined from top to bottom, and the opening of the flushing cavity 21 is gradually reduced from top to bottom, so as to change the potential energy of the water flow into power, ensure the speed of the water flow, and thus ensure the flushing force of the water flow, and make the cleaning easy. After the water flow washes the washing cavity 21, the water flow falls to the water sealing structure 26 and is discharged out of the toilet from the sewage discharge pipe 3. The water sealing structure 26 is used for preventing the back flow of the filth from the drainage pipe 3, thereby preventing the residual filth of the toilet bowl. Therefore, the present application ensures the flushing force of the water flow by setting one flushing jet orifice 221 to be communicated with the vortex guiding groove 23 and only weakening the flushing jet orifice 221, thereby ensuring the flushing cleanness and being beneficial to cleaning. Preferably, the water flow can flow along the vortex guiding groove 23 to form a water vortex without considering the jetting angle of the water flow, and only one flushing jet port 221 is provided, so that the time can be reduced in production and manufacturing, the production speed can be increased, and the production cost can be reduced.

Further, the drainage channel 22 further comprises a pressurization channel 222 and a main channel 223; the main runner 223 is arranged obliquely from top to bottom; the water inlet end of the main flushing channel 223 is communicated with the drain valve mounting port 11; a pressurizing water inlet 241 is formed in the water inlet end of the pressurizing flushing channel 222; the pressurizing flushing channel 222 is communicated with the main flushing channel 223 through the pressurizing water inlet 241; the flushing jet orifice 221 is arranged at the water outlet end of the pressurizing flushing channel 222, and the pressurizing flushing channel 222 is communicated with the vortex guide groove 23 through the flushing jet orifice 221; the cross-sectional area of the pressurized water inlet 241 is larger than the cross-sectional area of the flushing jet port 221. The discharge water passage 22 is divided into the pressurizing passage 222 and the main passage 223. Because the main wash way 223 is inclined from top to bottom and is low in front and high in back, when the water flow in the water storage cavity 12 flows from the drain valve mounting port 11 to the main wash way 223, the inclined arrangement of the main wash way 223 can convert the potential energy of the water flow into the kinetic energy, ensure the speed of the water flow and further ensure the flushing force of the water flow. After the main channel 223 is accelerated, the water flow enters the pressurizing channel 222. Because the cross-sectional area of the pressurized water inlet 241 is larger than that of the flushing jet orifice 221, the water inlet speed of the pressurized flushing channel 222 is larger than the water outlet speed thereof; and the main flushing passage 223 will continuously discharge water to the pressurizing flushing passage 222, so that the pressure of the pressurizing water inlet 241 will be greater than the pressure of the flushing jet orifice 221, so that pressure is formed in the pressurizing flushing passage 222, and the direction of the pressure is from the pressurizing well water inlet along the flushing jet orifice 221, so that the speed of water flow is increased, the impulsive force of the water flow is increased, and the flushing cleanness is ensured.

Preferably, the length of the pressurizing channel 222 ranges from 90mm to 120 mm. When the length of the pressurizing flushing channel 222 is less than 90MM, the pressure of the pressurizing flushing channel 222 on the water flow is too small, so that the acceleration of the water flow is small, the impulsive force of the water flow is insufficient, the force is insufficient when the flushing cavity 21 is flushed, and the flushing cavity 21 cannot be flushed completely. When the length of the pressurizing flushing channel 222 is greater than 120MM, the flowing time of the water flow in the pressurizing flushing channel 222 is too long, so that the pressurizing flushing channel 222 is long in water spraying time at the beginning, the flushing time is long, and the flushing efficiency is low. Therefore, when the pressurizing flushing channel 222 is arranged between 90MM and 120MM, the flushing force of water flow and the flushing efficiency can be guaranteed.

More preferably, the diameter of the flushing jet 221 ranges from 15 to 20 mm. When the diameter of the flushing jet orifice 221 is smaller than 15mm, the water yield of the pressurizing flushing channel 222 is low, the formed water vortex is small, the flushing time is long, the efficiency is low, and more seriously, when the water yield is high, the flushing force is insufficient, and the cleaning is not clean. When the diameter of the flushing jet orifice 221 is larger than 20mm, the pressure difference between the flushing jet orifice 221 and the pressurizing water inlet 241 is small, and the pressure of the pressurizing flushing channel 222 is low, so that the water flow momentum is low. Therefore, the diameter of the flushing jet port 221 preferably ranges from 15 to 20 mm.

Further, the drainage channel 22 is further provided with a siphon channel 225, and the siphon channel 225 is arranged obliquely downwards; the water sealing structure 26 is provided with a siphon jet hole 261; the water inlet end of the siphon flushing channel 225 is communicated with the main flushing channel 223; the water outlet end of the siphon flushing channel 225 is communicated with the water sealing structure 26 through the siphon jet hole 261; the sewage discharge pipe 3 is provided with a sewage discharge inlet 300, and the sewage discharge pipe 3 is communicated with the water sealing structure 26 through the sewage discharge inlet 300; the siphon injection hole 261 is disposed opposite to the soil exhaust inlet 300. Part of the water flow of the main flushing channel 223 enters the flushing cavity 21 from the pressurizing flushing channel 222, and the water flow of the flushing cavity 21 discharges the dirt on the surface of the flushing cavity 21 to the water sealing structure 26. And the other part of the water flow of the main flushing channel 223 flows to the siphon flushing channel 225 and is sprayed out from the siphon spraying hole 261 to the bottom of the water sealing structure 26 along the siphon flushing channel 225, so that the water sealing structure 26 generates siphon, and the sewage falling from the washing cavity 21 is washed into the sewage pipe 3 and then discharged to the toilet seat 2.

More preferably, the main passage 223 includes a first pressure increasing part 271 and a flow dividing part 272; the first pressurizing part 271 and the flow dividing part 272 are both arranged obliquely downwards; the first pressurizing part 271 is positioned right below the drain valve mounting port 11; the pressurizing water inlet 241 and the water inlet end of the siphon runner 225 are respectively communicated with the flow dividing part 272.

Specifically, the inclination angle of the first pressure increasing part 271 is in the range of 30 to 35 °; the angle of inclination of the diverging portion 272 ranges from 18 to 22 °.

As shown in fig. 5, the main passage 223 may be divided into a first pressurizing part 271 and a dividing part 272. The first pressurizing part 271 is arranged right below the drain valve mounting port 11, so that after water flow in the water storage chamber 12 flows into the main flushing passage 223 from the drain valve mounting port 11, potential energy of the water flow can be converted into power through the first pressurizing part 271, and the speed of the water flow is increased. And the inclination direction of the first pressure increasing part 271 is in the range of 30-35 degrees, so when the inclination angle of the first pressure increasing part 271 is larger than 35 degrees, the conversion rate of the water flow potential energy to the kinetic energy is low, and the speed of the water flow is low, resulting in that the flushing is not clean. When the inclination angle of the first pressurizing part 271 is less than 30 °, the distance between the first pressurizing part 271 and the drain valve mounting opening 11 is too small, which results in too little water inflow of the main flushing passage 223, thereby affecting the flushing efficiency. Further, when the water flow is accelerated in the first pressurizing part 271, the water flow of the main flushing passage 223 will form a branch flow in the branch part 272, and a part of the water flow will flow into the pressurizing flushing passage 222, and another part of the water flow will flow into the siphon flushing passage 225. The angle of the diversion portion 272 is 18-22 ° in this design, because when the water flow is greater than 22 °, the water flow of the main channel 223 will mostly flow into the siphon channel 225, and when the water flow of the pressure channel 222 is increased, the washing chamber 21 will not be cleaned. When the inclination angle of the diversion portion 272 is less than 18 degrees, most of the water flow of the main flushing channel 223 flows into the pressurizing flushing channel 222, which causes a small water inflow of the siphon flushing channel 225, which causes a small siphon force of the water sealing structure 26 plate, poor sewage discharge capability, and a possibility of residual dirt in the toilet bowl, thereby generating a bad smell.

Further, a second pressure increasing part 251 is further arranged at the water inlet end of the siphon flushing channel 225; the second pressurizing part 251 is arranged obliquely downwards, and the range of the inclination angle of the second pressurizing part 251 is 45-60 degrees, because the water flow loses a part of power after being shunted by the shunting part 272, the second pressurizing part 251 is arranged at the top end of the siphon flushing channel 225, the potential energy of the water flow is further converted into power, the water flow speed of the siphon flushing channel 225 is ensured, and the force for generating siphon is ensured.

Specifically, the water sealing structure 26 is provided with a dirt receiving projection 262; the top surface of the soil receiving protrusion 262 is an inclined surface with a front side higher than a rear side so that the top surface of the soil receiving protrusion 262 faces the soil inlet 300 of the soil discharge pipe 3. The dirt receiving protrusion 262 guides the dirt to the dirt inlet 300 better through the top surface, so that the water sealing structure 26 can flush the dirt into the dirt discharge pipe 3 more conveniently when siphon is generated, the flushing speed is increased, and the flushing efficiency is improved.

Preferably, the drain pipe is divided into an ascending pipe section 31, a first bend section 32, a second bend section 33 and a horizontal section 34 which are connected in sequence along the water flow direction; the waste inlet 300 is provided to the riser section 31; the drainage outlet 310 is disposed on the horizontal section 34, and the drainage outlet 310 is disposed downward. The riser section 31 is at a height from the horizontal end such that the water sealing structure 26 is more easily siphoned and the resulting siphon is stronger. And the water flow in the first bend section 32 and the second bend section 33 can convert potential energy into kinetic energy, that is, the water flow can be accelerated twice, so that the sewage discharge speed is improved. Therefore, the arrangement can realize easy pollution discharge and improve the conveying performance and the pollution discharge efficiency of the pollution discharge pipe 3.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
