Exempt from interconnecting piece 410 and the junction of outlet part 420 is too small, influences the flow of draining；Further avoid interconnecting piece 410 and outlet part
420 junction is excessive, and the junction of interconnecting piece 410 Yu outlet part 420 can not be effectively closed during causing sewage to be discharged,
And then closed air chamber can not be formed.
Specifically, the internal diameter of the junction of interconnecting piece 410 and outlet part 420 is 32mm.Certainly, in other embodiments,
The internal diameter of the junction of interconnecting piece 410 and outlet part 420 can also be more than or less than 32mm.
In one embodiment, by taking the diameter of storage chamber 210 is 125mm as an example, the diameter of water inlet pipe 100 is 50mm-80mm, out
The diameter 40mm-60mm of the outlet part of water pipe.So that the diameter ratio of the outlet part of the diameter and outlet pipe of water inlet pipe 100 is about
When 1.5, sewage is easy that air in storage chamber 210 and drainage cavity 220 is gradually discharged during discharge, and then is more easier to produce
Raw siphon effect, improves the efficiency of draining.During use, the diameter of general water inlet pipe 100 is bigger, then displacement is also got over
Fastly, it but needs to increase the diameter of storage chamber 210 simultaneously, will lead to the volume increase of floor drain discharge structure 10, increased costs in this way.
And if the diameter of the outlet part of outlet pipe increases, and is unfavorable for the discharge of air in drainage cavity 220 and storage chamber 210, in turn
Siphon effect is weak during will lead to draining.Meanwhile the increase of the diameter of the outlet part of outlet pipe also causes sewage to backflow wind
The increase of danger.Specifically, the diameter of water inlet pipe 100 is preferably 75mm, and the diameter of the outlet part of outlet pipe is preferably 50mm.
The displacement of floor drain discharge structure 10 in above-described embodiment is 30L/min-50L/min, and displacement is bigger, draining
Effect is more preferable.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but not
It can therefore be construed as limiting the scope of the patent.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
