Abstract

The utility model relates to a deodorant floor drain which comprises a main big bowl (3), a seal cover (2) with a water inlet (1), and a water outlet (6). The deodorant floor drain is characterized in that the central part of the main big bowl (3) is provided with an upwardly raised water storage depth limit ring (5), which forms a U-shaped pipe with a doliform covered bowl extending ring (4), and the limit ring (5), the water inlet (1) and the water outlet (6) form a drainage channel with enough clearance. Above all, the height h2 from the water storage depth limit ring (5) to the seal cover (2) is enlarged, and the height is strictly calculated according to hydromechanic principle. The deodorant floor drain is suitable for high buildings with 4 to 100 floors and can be used under a wind-speed of 40m/s (typhoon), and can solve the odor problem of the floor drain once for all.

Description

Odour-proof floor drain

Technical field

The utility model relates to a kind of improvement technology of floor drain, is used for the accomodation ground draining.

Background technology

Odour-proof floor drain is the equipment that solves the draining of building accomodation ground, to floor drain require one to be that enough unit interval displacement will be arranged, the 2nd, deodorant function be arranged.

At present, the odour-proof floor drain in market generally has two kinds of forms, and the one, traditional hydrolock odour-proof floor drain, the 2nd, valve-type odour-proof floor drain.Therefore tradition hydrolock odour-proof floor drain does not offset the negative pressure influence of high-rise building exhaust passage because of not in full conformity with fluid mechanics principle.When wind speed during greater than 4 grades, water seal is ineffective and leak smelly.Pondage Xiao Yi evaporation is withered in addition, loses the deodorization effect.Sound can take place in the valve-type odour-proof floor drain when air-flow differential changes, influence sealing when additional valves is hung foul, and life of valve is short.

Tradition hydrolock odour-proof floor drain is simple in structure because of it, long being widely used of life-span, owing to only consider the water degree of depth when traditional hydrolock odour-proof floor drain designs, ignore pressure reduction and stored height, therefore when outdoor wind speed increase, the suction function of exhaust passage, washroom makes the water in the floor drain water seal overflow ground to cause serious leakage smelly.

Summary of the invention

For overcoming the shortcoming and defect part of prior art, the utility model provides a kind of floor drain that is applicable to effective deodorization under high floor building and high wind speed (typhoon) environment.

The utility model comprises the main body jorum, has the capping of water inlet, delivery port, the core of main body jorum has the retaining degree of depth circle band that raises up, form the U-shaped pipe with barrel-shaped teabowl with a cover pull ring, same water inlet, delivery port constitute the drainage channel in enough gaps, main is has strengthened the height of retaining degree of depth circle band to capping, this highly according to fluid mechanics principle strictness calculate out.

The utility model is the odour-proof floor drain that uses down at the 4th～100 floor height buildings, 40 meters/S of wind speed (typhoon) environment.Its design is calculated through the hydrodynamics bernoulli equation according to attic wind speed and story height based on fluid mechanics principle, and original hydrolock odour-proof floor drain has been carried out improving design, increases the pressure reduction storage area height and the retaining degree of depth.Thoroughly solved high floor and caused leaking smelly problem because of negative-pressure sucking and the water evaporation that wind speed produces.

Description of drawings:

Accompanying drawing is the utility model structural representation.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

As shown in the figure, the utility model comprises main body jorum 3, has the capping 2 of water inlet 1, delivery port 6, the core of main body jorum 3 has the retaining degree of depth circle band 5 that raises up, and forms the U-shaped pipe constitutes enough gaps with water inlet 1, delivery port 6 drainage channel with barrel-shaped teabowl with a cover pull ring 4.

The utility model improves traditional hydrolock odour-proof floor drain, has increased pressure reduction storage area height and water storage depth structure, and as shown in the figure, h1+h3 is the water storage degree of depth among the figure, and h2 is a pressure reduction storage area height.Must satisfy national standard 50mm and h2＞h1+h3 by national standard h2.

P1＞p2 when washroom air exhaust passage pressure p 2 reduces, the p1 place water surface descends, p2 place water surface rising certain altitude, the pressure of this water column is offset (p1-p2) pressure, and the p2 place water surface is risen less than capping, thoroughly solves floor drain and leaks smelly problem.

Claims

1. odour-proof floor drain, comprise main body jorum (3), have capping (2), the delivery port (6) of water inlet (1), the core that it is characterized in that main body jorum (3) has the retaining degree of depth circle band (5) that raises up, form the U-shaped pipe with barrel-shaped teabowl with a cover pull ring (4), same water inlet (1), delivery port (6) constitute the drainage channel in enough gaps.
