Description

water replenishment sanitary floor drain

(1) Technical field

The utility model relates to a floor drain.

(2) Background technology

The National Building Water Supply and Drainage Design Code stipulates: "In toilets, washrooms, toilets and other rooms with drainage facilities, floor drains should be installed." Due to the small amount of water in the traditional floor drain, it is very easy to evaporate and dry up. Therefore, there are common problems in floor drains, such as dry water seal, broken seal, and odor, which are extremely harmful to indoor environmental hygiene.

The traditional floor drain has a shell that communicates with the water inlet and the drainpipe. The shell is covered with a grate, and a bell-shaped water seal is built in the shell. The seam enters the water, and the water flows through the partition flow channel. This structure greatly increases the water flow resistance, reduces the drainage capacity, and easily deposits debris to hinder the drainage function. Moreover, the water stored in the water seal is easy to evaporate, or the water seal is damaged due to pressure fluctuations in the pipe, resulting in rotten gas and harmful environmental sanitation. It has been a problem that has been difficult to solve for many years.

In order to solve the above problems, the protection water seal is often filled with water, and the only way to replenish the water loss of the water seal is. Although the multi-channel floor drain increases the chance of water inflow, it makes the wiring of the drainage pipe complicated and messy, and its shape is large, which is inconvenient for installation. At present, a large number of built floor drains do not have water replenishment equipment, and the water stored in the water seal is easy to evaporate and dry up, causing rotten gas, causing the problem of "over-flavor" to trouble users. If it is completely remodeled, the construction will be very difficult and interfere with the lives of users. But the washing machine socket on the sanitary floor drain or the multi-functional floor drain grate can be changed into the replenishment pipe water inlet, and the replenishment pipe is inserted on it to replenish water.

As early as the 1950s in the United States, the problem of water sealing and water replenishment was included in the NPC, that is, a water replenisher was installed on the faucet of the washbasin. With the use of the faucet, water was replenished to the water seal of the floor drain to block the rot in the drain pipe. Air enters the room to avoid pan-odor. However, the replenishment water used in this replenishment method is clean water. Although the water consumption is not large, it is also a waste of clean water. The use of waste water replenishment has dual meanings of water saving and environmental protection.
