According to the anti-odor method, floor drains are mainly divided into three types: water anti-odor floor drains, sealed anti-odor floor drains and three-proof floor drains. Water anti-odor floor drains are traditional and common to us. It mainly utilizes the sealing property of water to prevent the spread of odors. In the structure of floor drains, the water storage bay is the key. For such floor drains, it is advisable to choose those with a relatively deep water storage bay as much as possible. One should not merely focus on appearance. According to relevant standards, the body of the new type of floor drain should ensure a water seal height of 5cm and have a certain ability to keep the water seal from drying up to prevent the emission of foul odors. Nowadays, some ultra-thin floor drains have emerged in the market, which are very beautiful, but their anti-odor effect is not very obvious. If your bathroom space is not an open room, it is better to choose a more traditional one. A sealed anti-odor floor drain refers to adding an upper cover to the floating cover to seal the floor drain body and prevent odors. The advantage of this floor drain is its modern and avant-garde appearance, but the disadvantage is that you have to bend over to lift the cover every time when using it, which is rather troublesome. However, recently a improved type of sealed floor drain has emerged in the market. It is equipped with a spring under the upper cover. When in use, you can step on the upper cover with your foot, and it will spring up. When not in use, you can step on it again, which is much more convenient. The three-proof floor drain is the most advanced anti-odor floor drain to date. It installs a small floating ball at the lower end of the floor drain pipe. On a daily basis, it uses the water pressure and air pressure in the sewer pipe to hold the ball up, making it completely close to the floor drain opening, thereby playing a role in preventing odor, insects and water overflow.

Ii. Dimensions.

When real estate developers deliver houses, the reserved drainage holes are usually quite large and need to be adjusted by decoration workers. Many consumers choose floor drains based on the size of the drainage outlets adjusted by the decoration team after the decoration is completed. However, all the floor drains on the market are of standard sizes, so it is not uncommon to find satisfactory products. Therefore, it is reminded to consumers that they should select the floor drain they like during the design stage of decoration, and then install the drainage outlet according to the size of the floor drain. In addition, the opening diameter of the floor drain grate should be controlled between 6*8mm to prevent hair, sludge, sand particles and other dirt from entering the floor drain.

Thirdly, it should be noted that the number of water inlets for multi-channel floor drains should not be too large.

Multi-channel floor drains are products developed in recent years. One main body usually has 3 to 4 water intakes (for the washbasin, bathtub, washing machine and floor drainage). This structure not only affects the drainage capacity of the floor drain, but also does not conform to the actual design situation
