Preferably, sewage pipes is equipped with a slope section, a turn to section and a lower water section along the rivers direction in proper order, the slope section with the junction that turns to the section forms sewage pipes's highest position department, the trap is located down the lower water section.

Preferably, the bottom wall of the lower water section forms a concave pit, and the pit forms the lower trap.

Preferably, an overflow gap is formed between the water storage liquid surface of the lower water trap and the top wall of the corresponding lower water section.

Preferably, the height value H of the overflowing clearance is 20 mm-35 mm.

The utility model has the advantages that:

the utility model discloses through setting up two traps on direct-flushing formula closestool (the closestool that utilizes the pressure water of water pipe network directly to wash), compare prior art and increased lower trap, lower trap can make sewage pipes form full water state fast to produce the siphon in advance, under the condition of equal water source pressure value, can effectively improve the flushing effect, the pressure value at the required water source of the reduction closestool of doing, thereby enlarge the application scope of this type closestool.

Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following description of the present invention is provided with reference to the accompanying drawings, which are only some embodiments of the present invention, and it is obvious for a person skilled in the art to obtain other drawings without creative efforts.

As shown in fig. 1 to 3, the tankless toilet having a double trap includes a bowl portion 10, a first flushing water path (not shown) for cleaning an inner wall surface of the bowl portion 10, a second flushing water path (not shown) for cleaning a bottom of the bowl portion, and a drain pipe 20. The first washing water path communicates with a washing hole 40 provided at the top of the tub, and water flowing out of the washing hole 40 washes the inner wall surface of the tub 10. The second flushing waterway is communicated with a jet hole 30 formed at the bottom of the tub portion, and the jet hole 30 jets water toward the drain pipe 20. The first flushing waterway and the second flushing waterway are both supplied with water by a tap water pipe network, and the toilet without the water tank is directly flushed by using the pressure of tap water. The sewage draining pipeline 20 is sequentially provided with an upper trap 21 and a lower trap 22 (the dotted line in fig. 2 indicates the water stored in the traps) along the water flow direction, the upper trap 21 is arranged at the bottom of the basin 10, and the injection hole 30 and the inlet of the sewage draining pipeline 20 are communicated with the upper trap 21.

In this embodiment, the sewage pipe 20 is sequentially provided with an ascending section 20a, a turning section 20b and a launching section 20c along the water flow direction, the joint of the ascending section 20a and the turning section 20b forms the highest position a of the sewage pipe 20, and the launching trap 22 is arranged on the launching section 20 c. Specifically, in this embodiment, the bottom wall of the lower water segment 20c forms a concave depression that forms the lower trap 22.

In this embodiment, an overflow gap is formed between the water surface of the lower trap 22 and the top wall of the corresponding lower water segment 20c, the height value H of the overflow gap is preferably 20mm to 35mm, and the overflow gap has a better siphon forming effect in this value range, wherein the height value H of the overflow gap is further preferably 25 mm.

As shown in fig. 2, compared with the lowest pressure value of the single trap water tank-free toilet and the double trap water tank-free toilet at the highest point section of the sewage conduit, the lowest pressure value of the double trap water tank-free toilet at the highest point section of the sewage conduit is significantly smaller than the lowest pressure value of the single trap water tank-free toilet at the highest point section of the sewage conduit between 1.4 seconds and 2.2 seconds, and the maximum difference between the former and the latter is about-600 Pa, which also indicates that the siphon negative pressure formed by the sewage conduit of the double trap is larger, thereby helping to improve the flushing effect and reducing the pressure value of the water source required by the toilet.

As shown in fig. 3, compared with the average value of the lowest pressure at the highest point section of the sewage conduit in the single trap water-tank-free toilet and the double trap water-tank-free toilet, the average value of the lowest pressure at the highest point section of the sewage conduit in the double trap water-tank-free toilet is obviously smaller than the average value of the lowest pressure at the highest point section of the sewage conduit in the single trap water-tank-free toilet, and the maximum difference between the former and the latter is about-400 Pa, which indicates that the siphon negative pressure formed by the sewage conduit of the double trap is larger, thereby helping to improve the flushing effect and reducing the pressure value of the water source required by the toilet.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
