Abstract

The invention discloses a floor drain with a water storage cavity. The floor drain comprises a floor drain cover and a floor drain seat, wherein a running water channel and a water seal cover are arranged on the floor drain cover; a water seal pipe is arranged on the floor drain seat; the floor drain cover covers the floor drain seat; the floor drain seat is provided with an inner shell and an outer shell; the water storage cavity is formed between the inner shell and the outer shell; an air vent is formed on the floor drain seat above a water surface; and the lower end of the inner shell is lower than the water surface.

Description

Band storage chamber floor drain

Technical field

The present invention relates to a kind of water-seal floor drain and relate in particular to a kind of band storage chamber floor drain.

Background technology

Existing common water-seal floor drain great majority are dry seldom easily because of the water seal amount, thereby can not be at a distance from smelly.

Consult Fig. 1, existing common water-seal floor drain comprises drain cover 1, floor drain seat 4; Gutter channel 3 and water seal cover 2 are arranged on the drain cover 1; Shell 5 and water sealing (sealing water) pipe 6 are arranged on the floor drain seat 4, and drain cover 1 covers on floor drain seat 4, between shell 5 and water seal cover 2, water cavity A is arranged; Between water seal cover 2 and water sealing (sealing water) pipe 6, water cavity B is arranged, water cavity A is connected with water cavity B;

When there was water on ground, current flowed to water cavity A from gutter channel 3, flowed to water cavity B again; Flow in the water sealing (sealing water) pipe 6 then and the final ground of discharging, all have water in water cavity A and the water cavity B at ordinary times, be used in isolated dirty the pipe dirty air-flow to indoor; But the water in the water cavity A can vapor away through gutter channel 3 gradually; Though the water in the water cavity B can flow to water cavity A gradually, because the water yield in water cavity A and the water cavity B all seldom, so still can vapor away very soon; When water level was lower than water seal cover 2 lower ends, the dirty gas in the dirty pipe will flow to indoor.

Summary of the invention

The object of the present invention is to provide a kind of band storage chamber floor drain, it has bigger water seal storage, and is dry not too easily.

To achieve these goals, band storage chamber floor drain provided by the invention comprises drain cover, floor drain seat; Gutter channel and water seal cover are arranged on the said drain cover, on the said floor drain seat water sealing (sealing water) pipe is arranged, said drain cover covers on said floor drain seat; It is characterized in that: said floor drain seat has inner casing and shell; Between said inner casing and shell, storage chamber is arranged, on the said floor drain seat more than water seal face air vent is arranged, the lower end of said inner casing is lower than water seal face;

As the improvement of band storage chamber floor drain of the present invention, its further characteristic is: the lower end of said inner casing is not higher than the lower end of said water seal cover;

As the improvement of band storage chamber floor drain of the present invention, its further characteristic is: said air vent is on said inner casing.

The invention has the beneficial effects as follows:

Simple in structure easily manufactured, water seal water amount is big, at a distance from smelly effective.

The specific embodiment

The specific embodiment one

Consult Fig. 2, band storage chamber floor drain of the present invention comprises drain cover 1, floor drain seat 4; Gutter channel 3 and water seal cover 2 are arranged on the drain cover 1, inner casing 7 and shell 5 and water sealing (sealing water) pipe 6 are arranged on the floor drain seat 4, air vent 8 is arranged at inner casing 7 tops; Drain cover 1 covers on floor drain seat 4; Between inner casing 7 and water seal cover 2, water cavity A is arranged, between water seal cover 2 and water sealing (sealing water) pipe 6, water cavity B is arranged, between inner casing 7 and shell 5, storage chamber C is arranged;

Wherein, the lower end of inner casing 7 is equal with the lower end of water seal cover 2, and water cavity A and water cavity B and storage chamber C interconnect;

Consult Fig. 3, when there was water on ground, current flowed to water cavity A from gutter channel 3; Flow to water cavity B again, flow in the water sealing (sealing water) pipe 6 then and the final ground of discharging, owing to air vent 8 is arranged at inner casing 7 tops; So the water level when land drainage in the storage chamber C also can raise to some extent; Water level can descend again when draining finishes, and promptly the water in the storage chamber C is movable, is unlikely to become stagnant water;

All there is water in water cavity A and water cavity B and the storage chamber C at ordinary times; Be used for that dirty air-flow is to indoor in the isolated dirty pipe, the water in the water cavity A can vapor away through gutter channel 3 gradually, because storage chamber C internal upper part has only two slight air vents 8 to communicate with the external world; So it is few in the storage chamber C from the water yield of air vent 8 volatilizations; Water in the storage chamber C almost all can be used for supplementary feed chamber A, again because the water amount in the storage chamber C is relatively large, so dry not too easily.

The specific embodiment two

Fig. 2 and Fig. 4 are consulted in contrast; Fig. 3 and Fig. 5 are consulted in contrast; This specific embodiment two is that with the difference of the above-mentioned specific embodiment one the cover size of the drain cover 1 in this specific embodiment two is bigger than the cover size of the drain cover in the specific embodiment one 1, and the shape of the inner casing 7 of floor drain seat 4 changes to some extent; Air vent 8 positions on inner casing 7 tops are different; But the main storage chamber C that is used for retaining is variation not, so the basic volatilization prevention principle of this specific embodiment two and the above-mentioned specific embodiment one does not change, has and no longer repeats here to state on the way.

Claims
