a floor drain

Abstract

The invention belongs to building water supply and drainage systems, in particular to a novel floor drain comprising a main pipe. The bottom end of the main pipe is closed. One side of the bottom of the main pipe is provided with a drain pipe and an inflow pipe; the drain pipe and the inflow pipe are integrally connected; the inflow pipe is higher than the drain pipe; the drain pipe is curvilinearly bent in shape. A water supply distributor box module is connected to the top end of the main pipe; the top end of the water supply distributor box module is provided with a top cover; the middle of the top cover is provided with a vertical drain pipe. The bottom of the water supply distributor box module is provided with a round through hole; the vertical drain pipe penetrates the round through hole and extends down; the bottom end of the vertical drain pipe is located between the inflow pipe and the drain pipe. The novel floor drain has the functions of drainage, water supply and deodorization, produces low sound of flowing water during drainage, is convenient to maintain later after installation, and allows pipe blockage to be removed without using pipe dredging equipment.

Description

technical field [0001] The invention is mainly applied to water supply and drainage systems of buildings, and can be installed in bathrooms, toilets and balconies to connect with drainage equipment such as washbasins, bathtubs and floor drains, and especially relates to a floor drain. Background technique [0002] The floor drain is an important system of residential drainage pipes. It is an important interface connecting the drainage pipe system and the indoor ground. Its performance plays an important role in the indoor air quality. A small floor drain is related to a big problem with the quality of life. Ordinary floor drains usually overflow. The water passing section of the floor drain is not smooth enough, the sewage cannot pass through quickly, or the internal structure of the floor drain is uneven, and dirt such as hair and fibers are caught, which may cause the floor drain to overflow. Ordinary floor drains are connected to the drainpipe of the U-shaped water storag...

Problems solved by technology

Ordinary floor drains usually overflow, the water passing section of the floor drain is not smooth enough, the sewage cannot pass through quickly, or the internal structure of the floor drain is uneven, and dirt such as hair and fibers are caught, which may cause the floor drain to overflow

Ordinary floor drains are connected to the drainpipe of the U-shaped water storage bend under the floor to retain a certain water source to form a water seal to block air circulation. However, when not in use for a long time, the water seal will evaporate or breed bacteria, which will also reduce the indoor ambient air. Moreover, the water seal of the U-shaped water storage bend will often be blocked, and maintenance after the blockage is troublesome, and the use of large-diameter sewage pipes is a waste of materials. In addition, ordinary floor drains need to be hoisted on the pipe entity to carry Drainage pipes are used to reduce the gravity of the floor drain. The construction is troublesome, and holes need to be drilled and metal parts are used for hoisting, resulting in an increase in material and labor costs.
