Floor drain

Abstract

The invention discloses a floor drain, and belongs to the technical field of household article antennas. The floor drain comprises a water outlet assembly, a water storage assembly and a water inlet assembly, the water inlet assembly comprises a first water inlet pipe, a second water inlet pipe and a third water inlet pipe which are all vertically arranged and connected in a leghth decreasing mode, the water outlet assembly comprises a second water outlet pipe, a first water outlet pipe and a third water outlet pipe which are vertically arranged and are sequentially decreased in length, the water storage assembly is a sealed water storage tank, the top of the third water outlet pipe is parallel to the top of the second water outlet pipe and communicates with the top of the second water outlet pipe, and the bottom of the second water outlet pipe is parallel to the bottom of the first water outlet pipe and communicates with the bottom of the first water outlet pipe. The floor drain is long in service life, high in drainage speed and good in water sealing effect.

Description

technical field [0001] The invention relates to the technical field of household articles, in particular to a floor drain. Background technique [0002] The floor drain is an important interface connecting the drainage system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of the indoor air, and is very important for the odor control in the bathroom. The traditional water-sealed floor drain is a bell-type structure, that is, a buckle bowl is buckled on the mouth of the sewer pipe to create a "buckle cup"-shaped trap to achieve the purpose of sealing, so it is called "water seal". It has the following problems: [0003] 1. Odor pollution [0004] (1) The height of the water seal is not enough, most of which are only 10-20mm, and it is easy to dry up, causing the odor in the drainage pipe to overflow into the room. [0005] (2) In cloudy or windy weather, the air pressure is constantly changing...

AI Technical Summary

Problems solved by technology

[0003] 1. Odor pollution

[0004] (1) The height of the water seal is not enough, most of which are only 10-20mm, and it is easy to dry up, causing the odor in the drainage pipe to overflow into the room

[0005] (2) In cloudy or windy weather, the air pressure is constantly changing, the positive pressure in the pipeline will cause the bowl to float up, and the odor will overflow from the water; while the negative pressure in the pipeline will destroy the water seal and the pipeline will lose barrier, the odor will also overflow into the room

[0006] 2. Spread of pests and germs

The unstable water storage in the water-sealed floor drain has poor resistance to pests and germs such as mantis and black-winged insects that breed in the sewer pipes, endangering people's health

[0008] 3. The drainage speed is slow

[0009] The water flow must pass through a very narrow circular gap, and can only be discharged through two sharp turns of 180° on the lower and upper sides, which reduces the speed of the water flow and easily deposits dirt
