Description

technical field [0001] The invention relates to an accessory of a same-floor drainage system for houses and residences, in particular to an odor-proof floor drain. Background technique [0002] As an important part of the drainage system in houses, the floor drain is small, but it involves thousands of households and is related to people's health and environmental sanitation. [0003] It is generally believed that the floor drain is sufficient as long as it can bear the scattered water on the ground. Therefore, it has not been paid attention to by various relevant parties and there is a lack of special research on the structure and performance of the floor drain itself. Such as figure 1 Shown is a kind of traditional floor drain structure, this floor drain comprises drain body 11, downpipe 12, buckle bowl 13, floor drain body cover 14, and floor drain is installed in floor board 15 and decorative layer 16, and downpipe 12 is installed in The drain pipe 17 under the floor p...

AI Technical Summary

Problems solved by technology

[0004] (1) The floor drain is only suitable for laying pipes in the interlayer, that is, the floor drain is installed on the floor, and the drain pipe is installed under the floor, which cannot meet people's requirements for the net height and ergonomics of the bathroom

[0005] (2) The water seal height and water storage capacity of the floor drain are not enough (some floor drains have no water seal), and it is easy to dry up, causing the odor in the drainage pipe to flood into the room

[0007] (4) The self-cleaning ability of the floor drain is poor, and it is easy to catch hair and sludge, causing blockage

[0008] (5) The structure of the floor drain is unreasonable, the ability to maintain the water seal is poor, and the water seal is easily damaged by the negative pressure formed in the drainage pipe system

[0009] (6) The form of the floor drain is single, which cannot meet the requirements of the increasing level of residential design and the increase of water appliances
