Floor drain

Abstract

The invention discloses a floor drain. The floor drain solves the technical problem that the existing floor draining water is slow and the ground is easy to accumulate water, and belongs to the technical field of drainage device manufacturing. The floor drain comprises a floor drain body, and the floor drain body includes a first drain chamber and a second drain chamber; the top of the first drainage chamber is provided with a surface sewage inlet; a bottom water pipe connection is provided at a bottom or a side of the second drainage chamber; the bottom surface of the second drainage chamberis not higher than the bottom surface of the first drainage chamber, and the first drainage chamber and the second drainage chamber are connected through the drainage chamber connection port, and thedrainage chamber connection port is disposed on the bottom surface or the side surface of the first drainage chamber; a unidirectional drainage device is installed at the connection port of the drainage chamber, and the surface sewage is unidirectionally flowed into the second drainage chamber from the first drainage chamber through the one-way drainage device, and then discharged into the lower water pipe through the lower water pipe interface. The floor drain can drain at a faster speed with a larger drainage space, and has the function of not returning water to the ground when connecting the drain of the washing machine.

Description

technical field [0001] The invention relates to the technical field of drainage device manufacture, in particular to a floor drain. Background technique [0002] In daily life, the floor drain is an important interface connecting the sewer pipe and the floor of the indoor bathroom. As an important part of the drainage system in the residence, the performance of the floor drain directly affects the quality of the indoor air, which is very important for the odor control in the bathroom. [0003] With the development of the times, people's requirements for the quality of life are getting higher and higher, and the traditional water-sealed floor drains are gradually replaced by various new odor-proof floor drains. [0004] In the prior art, the anti-odor device of the anti-odor floor drain is usually installed in the sewer pipe. Due to the limitation of the diameter of the sewer pipe or the structure of the anti-odor device, the drainage speed of this type of floor drain is usua...
