The floor drain is something that drains water out of the bathroom, and its role is not generally large. The floor drain is an important interface connecting the drainage pipe system and the indoor floor. As an important part of the drainage system in the residence, its performance directly affects the quality of indoor air, and is very important for the control of odor in the bathroom. Although the floor drain is small, there are many issues to consider when choosing a suitable floor drain.
Under the premise that the existing building structure cannot be changed, floor drain deodorization should be a good way to solve the odor problem. How to deodorize the floor drain? Then we must first understand its structure. Ordinary floor drains generally include a floor drain body and a floating cover. The floor drain body refers to the part of the floor drain that forms a water seal, and the main part is the water storage bay. Since many floor drains are mainly deodorized by water seals, the depth of the structure and whether the design is reasonable determine the sewage discharge capacity and anti-odor capacity of the floor drain. When there is water in the floating cover, it can float up and down with the water in the floor drain. Many floating covers are additionally connected to the bell cover. When there is no water or there is little water, the sewer pipe is closed to prevent the odor from returning to the room from the sewer pipe.

The use of floor drains is divided into exclusive use functions, and floor drains are divided into two types: general use and washing machine special.
The floor drain for washing machines has a round hole in the middle, which can be inserted into the drain pipe, covered with a rotatable cover, which can be covered when not in use and unscrewed when used, which is very convenient, but the deodorant function is not as good as that of ordinary floor drains. However, since experts recommend not to set and install too many floor drains in the room, there are also some floor drains that are dual-purpose.
There are three types of floor drains on the market: stainless steel floor drains, PVC floor drains and all-copper floor drains.
Since the floor drain is buried below the ground and requires good sealing, it cannot be replaced frequently, so it is very important to choose the appropriate material. Among them, all-copper floor drains have begun to occupy a larger and larger share because of their performance. Stainless steel floor drains have been popular in the past few years because of their beautiful appearance, but according to relevant professionals, stainless steel is expensive and has a thin coating, so it will not escape the fate of rust after a few years; and pvc floor drains are cheap and have good deodorant effect. Yes, but the material is too brittle and easy to age, especially in the winter in the north where the temperature is low, and it needs to be replaced after a long time, so the market is not optimistic; at present, most of the copper chrome-plated floor drains are on the market. The patina has grown and it is easier to clean. Under normal circumstances, an all-copper floor drain can be used for at least six years.
