Description

Water seal type floor drain

Technical Field

The field of furniture manufacturing.

Background

The invention relates to a water seal type floor drain. Compared with the water-sealed floor drain sold in the market at present: the structure of the key points is different. Compared with the existing water-sealed floor drain on the market, the water-sealed floor drain provided by the invention has the advantages that: the water draining is fast, the anti-blocking capability is strong, the deodorization is good, and the water draining device is durable for a long time.

The water-sealed floor drains sold on the market at present are divided into two types:

the first type is: the annular water seal groove structure floor drain is characterized in that the water seal part of the annular water seal groove structure floor drain is an annular water groove, water flows into the annular water seal groove from the periphery of the annular water seal groove after flowing into the floor drain downwards from a peripheral leak hole of the water seal cover, and the water flows upwards after turning to the center at the bottom of the annular water seal groove and then is discharged from a middle overflow outlet of the annular water seal groove. As shown in fig. 2.

The second type: the water seal part of the floor drain is a water pool, and water flows to the center of the water pool, is poured into the water pool, turns around at the bottom of the water pool, then flows upwards from the periphery of the water pool, and is discharged from an overflow outlet at the periphery of the water pool. As shown in fig. 3.

The two water-sealed floor drains sold in the market at present are both in a circumferential symmetrical shape on the horizontal section, and the water flow is also in a circumferential symmetrical shape on the horizontal section. The difference between the floor drain of the invention and the two floor drains is that the water seal part is not a water pool or water tank structure with a symmetrical circumference, but a U-shaped pipe structure with two ports.

There is once published floor drain patent publication No. CN 201850633U. The floor drain invented by the publication number CN201850633U is characterized in that: the U-shaped pipe is arranged in a shell, and the lower opening of the shell is connected with a sewer pipe. The floor drain is arranged on a sewer pipe, is used in modern residential buildings, is higher than the floor of a floor slab, is suitable for hand basin drainage and is not suitable for ground drainage. In order to ensure a drainage gap, the casing outside the U-shaped pipe cannot be too small.

The difference between the floor drain of the invention and the floor drain of patent publication No. CN201850633U is that: firstly, a shell is not arranged outside the U-shaped pipe, and a drainage gap is formed between a drainage port of the U-shaped pipe and the inner wall of a sewer pipeline; secondly, the thin edge of the uppermost edge of the floor drain is connected with the vertical sewer pipe upper pipeline opening, and the rest part of the floor drain extends into the sewer pipe. Such improved benefits are: firstly, the floor drain is convenient to install, and the whole height of the floor drain is lower than the floor surface of a floor slab; and secondly, the water outlet is not shielded by the shell, so that the water discharging gap is conveniently enlarged, and the through-flow diameter of the U-shaped pipe is conveniently enlarged.

Disclosure of Invention

The water-seal floor drain is arranged in a vertical downward sewer pipe, and the convex edge is hung at the upper pipe opening of the sewer pipe and connected with the sewer pipe, so that the mounting height is not higher than the floor of a floor slab, and the water-seal floor drain can be used for draining water and insulating odor on the ground.

The floor drain consists of two parts, namely a floor drain frame and a floor drain core. The floor drain frame is similar to a basin shape, the upper edge is hung on the pipe orifice of the sewer pipe by a stretching edge stretching around, and the bottom surface is provided with a through hole. The floor drain core is a U-shaped pipe with two ends unequal in height, and the high-level port of the U-shaped pipe is provided with a convex edge protruding around. When the floor drain is used, the floor drain core is inserted into the hole on the bottom surface of the floor drain frame, the convex edge of the floor drain core is hung on the bottom surface of the floor drain frame, and a drainage gap is formed between the low-position drainage port of the floor drain core and the inner wall of the sewer pipe. When in use, the water stored in the U-shaped pipe of the time leakage core is used as a water seal to isolate odor.
