Hose sealed floor drain

Abstract

The invention relates to a hose sealed floor drain comprising a floor drain cover, a floor drain main body and a plastic hose. One end of the plastic hose is fixed on the floor drain main body and asa water inlet; and the other end of the plastic hose is a free end as a water outlet. The hose sealed floor drain is opened and closed by the change of a stream entering the floor drain and has the advantages of rapid switching, little stream passing resistance, good sealing effect, hard blockage, simple structure, low manufacture cost, and the like.

Description

technical field [0001] The invention relates to a floor drain, in particular to a hose-sealed floor drain. Background technique [0002] The traditional water-sealed floor drain is a bell-type structure, that is, a buckle bowl is buckled on the mouth of the water pipe to form a water seal, so as to achieve the purpose of sealing. Its main disadvantage is that the height of the water seal is relatively low, most of which are only 10-20mm, and it is easy to dry up, so that the odor in the drainage pipe returns to the room. Even if the water seal is deepened to 50mm, it will not delay the period of no odor for a few days, and the deepening of the water seal will make the hydraulic conditions worse and the deposition of dirt will be more serious; second, the positive pressure in the pipeline will cause the buckle bowl to float , the odor overflows from the water; and the negative pressure in the pipeline will destroy the water seal, the pipeline will lose its barrier, and the o...

Its main disadvantage is that the height of the water seal is low, most of which are only 10-20mm, and it is easy to dry up, so that the odor in the drainage pipe returns to the room

Even if the water seal is deepened to 50mm, it will not delay the period of no odor for a few days, and the deepening of the water seal will make the hydraulic conditions worse and the deposition of dirt will be more serious; second, the positive pressure in the pipeline will cause the buckle bowl to float , the odor overflows from the water; and the negative pressure in the pipeline will destroy the water seal, the pipeline will lose its barrier, and the odor will overflow into the room; the third is a large number of small solid impurities (such as sediment, hair, etc.) , cloth strips, paper scraps, etc.), will stick and settle in the water seal, and accumulate over time, these residues will become a breeding ground for germs and odors, and the water seal floor drain is harmful to black winged insects and other pests that breed in the sewer pipes. Some germs cannot be stopped at all; Fourth, the self-cleaning ability is poor, and the sticky and precipitated dirt in the water seal is very difficult to self-clean, and regular manual cleaning is required; Fifth, the hydraulic conditions are poor, the drainage is slow, and the water flow must pass through a very narrow loop The gap can only be discharged through two sharp turns of 180° up and down
