Siphon floor drain

Abstract

The invention discloses a siphon floor drain, comprising a siphon type main body and a plug; the siphon type main body is a casing with an upper opening, one side of the inner cavity of the casing is provided with a water discharge table, and the other side of the inner cavity of the casing is a water trap; An inverted U-shaped flat siphon pipe is arranged on the water table, and the flat siphon pipe includes a water inlet pipe, a curved pipe connected to the end of the water inlet pipe, and a water outlet pipe connected to the end of the curved pipe; The water pipe is communicated with the outlet of the water trap, and the end of the water outlet pipe is provided with a straight water outlet and a horizontal water outlet; the plug is installed on the straight water outlet or the horizontal water outlet. This application adopts the principle of toilet siphon type, and sets up an inverted U-shaped flat siphon pipe and a water trap on the siphon type body, so as to perfectly realize the design of the siphon pipe in the smallest space possible, and can achieve a higher flow rate when the water volume surges. On the other hand, due to the function of the water trap, it can prevent the odor blocking the sewer from going up.

Description

technical field [0001] The invention relates to a sanitary fitting technology, in particular to a siphon floor drain. Background technique [0002] At present, 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 life quality of the people in the house. [0003] The national standard for the water seal height of the floor drain is 50mm, but the water seal height of most water-sealed floor drains on the market is only 10-20mm, and the anti-odor effect is poor; the traditional water-sealed floor drain is a bell-shaped structure, that is, a buckle bowl (bell) is used Buckle on the mouth of the downpipe to create a "U"-shaped trap to achieve the purpose of sealing, so it is called "water seal". According to the investigation, the bell-type floor drain has shallow water seal and t...

[0003] The national standard for the water seal height of the floor drain is 50mm, but the water seal height of most water-sealed floor drains on the market is only 10-20mm, and the anti-odor effect is poor; the traditional water-sealed floor drain is a bell-shaped structure, that is, a buckle bowl (bell) is used Buckle on the mouth of the downpipe to create a "U"-shaped trap to achieve the purpose of sealing, so it is called "water seal"

According to the survey, the bell-type floor drain has the disadvantages of shallow water seal and easy throwing of bowls. In the toilets of many hotels,
