Siphon floor drain

Abstract

The invention discloses a siphon floor drain. The siphon floor drain comprises a main siphon-type body and a plug; the main siphon-type body is a shell with an open upper portion, a drainage table isarranged on one side of an inner cavity of the shell, and the other side of the inner cavity of the shell is a drain trap; a reversely U-shaped flat siphon is arranged on the drainage table and comprises a water inlet pipe, a bent pipe which is connected to the tail end of the water inlet pipe and a water outlet pipe which is connected to the tail end of the bent pipe; the bent pipe is convexly arranged on the drainage table, the water inlet pipe is communicated with an outlet of the drain trap, and a direct-discharge water outlet and a horizontal-discharge water outlet are formed in the tailend of the water outlet pipe; the plug is arranged at the direct-discharge water outlet or the horizontal-discharge water outlet. According to the siphon floor drain, a toilet siphon principle is adopted, the reversely U-shaped flat siphon and the drain trap are arranged on the main siphon-type body, the design of a siphon pipe is perfectly achieved in the space as small as possible, the high flowcan be achieved, and when the water amount is increased, drainage can be accelerated, and it is guaranteed that a house is not flooded by water; on the other hand, due to the effect of the drain trap, the bad smell of a sewer can be prevented from upward diffusing.

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...

AI Technical Summary

Problems solved by technology

[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, hotels, residences and other residential and public buildings, the floor drain has become a vent hole, and the harmful gas in the sewage pipe Escaping into the room, polluting the indoor environmental sanitation

Although some companies have deepened the water seal depth on the basis of the old-fashioned bell-jar floor drains, the engineering practice has proved that the biggest disadvantage of these floor drains is that the water flow channel is narrow, curved, and easy to block, and people have to disassemble the inner core. Causes the loss of water seal and pollutes the indoor environment
