Bathroom caisson secondary drainage floor drain pre-embedded system

Abstract

The invention relates to an embedding system for a secondary drainage floor drain of a toilet caisson. The system comprises a first base, a floor drain cover and an upper sewage discharge pipe. The first base is hollow, a circle of water storage wall is arranged in the first base, a cavity for water feeding and storage is formed between the inner wall of the first base and the outer wall of the water storage wall, and the inner side of the water storage wall is provided with a drainage channel. When the water level in the cavity is higher than the height of the water storage wall, water in thecavity can be discharged via the drainage channel. The floor drain cover is embedded in the first base and provided with water inlets for water leakage and an upper connection port, a water seal cover is arranged below the floor drain cover, and the water seal cover extends into the cavity. The upper sewage discharge pipe comprises a main pipe body and a drainage structure located on the main pipe body, the main pipe body penetrates through the upper connection port and is inserted in the water storage wall, and the drainage structure is used for draining water flowing down from the inner wall of the main pipe body into the cavity. According to the embedding system, a small part of water in the sewage discharge pipe is introduced into the floor drain, so that the liquid level of a water seal of the floor drain is sufficient, and the anti-odor effect is achieved.

Description

technical field [0001] The invention relates to the technical field of floor drains, in particular to a pre-embedded system for secondary drainage floor drains of toilet caissons. Background technique [0002] The floor drain is an important interface connecting the sewer system and the indoor ground. As an important part of the residential drainage system, its performance directly affects the quality of the indoor air, and is even very important to the healthy quality of life of the people in the house. [0003] An important indicator of the performance of the floor drain is deodorization, and the floor drain with the best deodorization effect is a water-sealed floor drain (water seal: use the water-sealed cover under the floor drain cover to contact the water stored in the floor drain to block the air flow inside and outside the floor drain) In order to resist sufficient positive pressure, the water seal floor drain often has a relatively high water seal height, but due to...

[0003] An important indicator of the performance of the floor drain is deodorization, and the floor drain with the best deodorization effect is a water-sealed floor drain (water seal: use the water-sealed cover under the floor drain cover to contact the water stored in the floor drain to block the air flow inside and outside the floor drain) In order to resist sufficient positive pressure, the water seal floor drain often has a relatively high water seal height, but due to the normal evaporation of water, the water seal structure will be destroyed when the evaporation is large, resulting in the failure of the deodorization function, especially in summer will make this disadvantage more obvious

In addition, the installation position of the drain pipe of the embedded floor drain cannot be adjusted, and the exhaust pipe sometimes cannot be aligned with the mounting seat
