Technical Field

The invention relates to the field of bathrooms, in particular to a squatting pan and a squatting pan flushing system.

Background

In the conventional flushing system of the squat toilet, as shown in fig. 1, in a normal water stop state, the outside air is communicated with a drain valve base drain port 1002 through an overflow pipe 1001, and the outside air is communicated with a drain pipe outlet 1004 through a ceramic body water passage pipe 1003. When the drain valve is opened, water flows out through the valve base drain port 1002, and when the valve base drain port 1002 is normally used, the valve base drain port 1002 is communicated with outside air through the overflow channel, negative pressure can be generated in the drain channel 1005 during drainage, and air can be mixed into the valve base drain port 1002 together under the action of outside atmospheric pressure, so that the drain channel 1005 cannot store water, the drainage speed is reduced, and when the squatting pan is flushed, the water in the drain channel 1005 can extrude air to generate noise.

Disclosure of Invention

In view of the above problems, an object of the present invention is to provide a squatting pan and a flushing system thereof, which solve the technical problems of "the decrease of the drainage speed and the noise of drainage caused by the mixing of the external air into the drainage channel" in the background art.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:

a squatting pan comprises a squatting pan ceramic body, wherein a urinal is arranged at the top of the squatting pan ceramic body, a submerged bay is arranged at the bottom of the urinal, and the submerged bay is connected with a sewage discharge siphon. The top of the urinal is provided with an annular flushing pipeline along the edge in a surrounding way, and the wall surface of the annular flushing pipeline is provided with a flushing hole group. The squatting pan ceramic body's inside is equipped with and is used for isolated outside air to wash the space of depositing water that the pipeline got into the water tank drain pipe from the annular, the bottom position in the space of depositing water is less than the annular washes the pipeline, deposit water space upper portion with the annular washes the pipeline and is linked together, sets up the water inlet that is used for being connected with the water tank drain pipe on the lateral wall in the space of depositing water.

In one embodiment, the water holding space is a trap, and the water inlet is positioned below the set of flushing holes.

In another embodiment, the water holding space is a trap, and the water inlet is positioned higher than the flushing hole set. The inside of the trap is fixedly provided with a water baffle for separating the water inlet and the annular flushing pipeline at two sides, the top of the water baffle is hermetically connected with the top wall surface of the trap, the bottom of the water baffle is provided with a water flowing notch for communicating the water inlet and the annular flushing pipeline, and the position of the end surface of the bottom of the water baffle is lower than that of the flushing hole group.

In another embodiment, the water storage space is an S-shaped conveying pipe, and the position of the water inlet is lower than that of the flushing hole group. And the bottom inlet of the S-shaped conveying pipeline is connected with the water inlet, and the top outlet of the S-shaped conveying pipeline faces the annular flushing pipeline and is lower than the annular flushing pipeline. The end face of the outlet side of the top of the S-shaped conveying pipeline is arranged rightwards and downwards in a downward inclined mode.

Preferably, an obtuse included angle formed between the end face of the outlet side of the top of the S-shaped conveying pipeline and the horizontal plane is 120-145 degrees.

Further, the flushing hole group comprises one or more first flushing holes for flushing the peripheral wall of the urinal and one or more second flushing holes for flushing the submerged bay. The first flushing hole is arranged at the side edge of the annular flushing pipeline and faces the peripheral wall of the urinal, and the second flushing hole is arranged at the bottom of the annular flushing pipeline and faces the sinking bay.

Furthermore, the water storage space is arranged at one side close to the submerged bay inside the ceramic body of the squatting pan.

The invention also discloses a squatting pan flushing system which comprises the wall-mounted water tank, a drain pipe and the squatting pan, wherein one end of the drain pipe is communicated with the bottom of the wall-mounted water tank, and the other end of the drain pipe is connected with a water inlet of a squatting pan ceramic body.

Further, a drain valve is installed at the bottom of the wall-mounted water tank, a drainage channel communicated with the drainage pipe is arranged at the bottom of the drain valve, and a sealing driving piece used for opening or sealing and closing the drainage channel is arranged inside the drain valve.

Further, an overflow pipe is fixedly mounted on the side edge of the drain valve, an overflow channel is arranged in the overflow pipe, one end of the overflow channel is communicated with the wall-mounted water tank, the other end of the overflow channel is communicated with the drain channel of the drain valve, an overflow device used for isolating outside air is mounted at the top of the overflow pipe, and an overflow cap used for preventing vortex generation is mounted at a water inlet of the overflow device.

The invention has the following beneficial effects: through setting up the water space of depositing in the inside of squatting pan ceramic body, the space of depositing water has isolated outside air and has got into the water tank drain pipe through annular flushing line. The overflow device isolates the communication between the outside air and the water outlet of the drain valve base through the overflow pipe. Therefore, when the drain valve drains water, because the air pressure in the drainage pipeline is less than the air pressure of the outside air, water can be stored in the drainage pipeline after the water is flushed at each time, and when the squatting pan is flushed next time, the pre-stored water in the drainage pipeline can directly act on flushing, so that the stroke of water is saved, and the flushing effect can be greatly improved. The air is not mixed in the drain pipe, so that the noise of the work of the wall-mounted water tank is greatly reduced. When the water storage space is an S-shaped conveying pipeline, the end face of the outlet side at the top of the S-shaped conveying pipeline is arranged to be inclined rightwards and downwards to form a proper opening angle, so that the water quantity can be reasonably and effectively distributed to each flushing position, the time difference of flushing water of each jet orifice collected in the toilet is short, the utilization rate of the water quantity participating in siphoning of the squatting pan is high, and the siphoning effect is good.
