Abstract

The invention discloses a pedestal pan. The pedestal pan is characterized in that a pipe orifice (2) at the bottom of a pedestal pan body (6) is connected with a water return tank (5), a float ball (1) is arranged at the upper end of the water return tank (5) and connected with a pull hook (3), the pull hook (3) is connected with a button (9), air exchange cavities (10) are arranged on two sides of the pedestal pan body (6), a water tank (12) is arranged above the seat (8) of the pedestal pan body (6), and a negative pressure unit (11) is connected to the water tank (12). The pedestal pan has the advantages that the pedestal pan is provided with the negative-pressure whirling air flow structure, negative-pressure air flows are formed at the seat of the pedestal pan to suck away excretion odor, the float ball of the pedestal pan can prevent high-rise air pressure backflow, and the pipeline of the float ball can prevent high-rise water pressure backflow.

Description

A kind of water closet

Technical field

The present invention relates to the deodorization design of water closet, especially a kind of negative pressure deodorization and buoy isolation structure.

Background technology

Along with improving constantly of living standard, dwelling environment is constantly improved, people more and more start to pay close attention to indoor environment problem, the mankind spend in indoor more than at least 70% time according to statistics, and the time that urban population is spent in indoor has exceeded 90%, especially infant and the old and the weak handicapped person longer in the time of indoor.But the concentration of indoor air pollutants is generally 2 ~ 5 times of outdoor pollutant levels, be dozens or even hundreds of times of outdoor pollutant in some cases.

Especially the place such as lavatory pan or toilet, excretion produce foul smell often can only volatilize in the space of lavatory less than 20 square meters, be also the one of washroom air is polluted,

And for use toilet, also there is corresponding problem, the elevator floor of current all kinds of high level is made up of the toilet of total sewer pipe and each floor, find in reality investigation, due to the design of too high elevator floor, when floor occupancy rate reaches after 90%, high-rise blowdown is accumulative to be got rid of downwards, have and necessarily may produce the shutoff of indirect sewer pipe, general the closer to bottom, pressure is larger, although state-of-the art blow-off line has had correlation technique to solve water reflux problem, but the air pressure produced but cannot solve, and general toilet takes a kind of U-tube road to be connected with main pipeline, after using for many years, U-tube road easily produces dirt, when being subject to external pressure extruding again, be easy to ducted foul smell and dirt press-in toilet, affect environment of toilet health.

Summary of the invention

The technical problem to be solved in the present invention is: provide a kind of water closet, there is negative pressure gyration airflow structure, form negative-pressure air-flow at water closet toilet seat, siphon away excretion foul smell, the float ball of water closet can prevent high-rise air pressure from refluxing, and its pipeline can prevent high-rise hydraulic pressure from refluxing.

The technical solution used in the present invention is: a kind of water closet, comprise water closet, the mouth of pipe bottom water closet is connected with return flume, there is float ball return flume upper end, float ball is connected with drag hook, and drag hook is connected with button, and the both sides of water closet are provided with ventilation lumen, be water tank above the cushion of water closet, water tank is connected with Negative pressure machine.Float ball 20mm ~ 35mm larger than the water closet mouth of pipe.Button is horizontal stripe structure.

Gyration airflow structure is a kind of typical negative inspiratory pressure structure, utilize be excretion time produce waste gas generally move up, so necessarily pass toilet seat pad when waste gas moves up again, so utilizing negative pressure to be sucked by waste gas is clear up in the delivery port passage of toilet originally, and adopt an exhalant canal circled round can produce the current of rotation, coordinate the current that toilet tanks internal drainage produces, very easily the excreta in toilet can be sucked return flume, simultaneously, the rotating channel of draining can be supplied to again the effect of Negative pressure machine circulating current, circulating current through a ring around after, do not need to return Negative pressure machine gas outlet, directly by the drainage pipe after fumer row U-type groove structure as similar in closestool bottom, direct importing sewer pipe.

Float ball 25mm ~ 35mm about larger than toilet drain passage, perfectly can block the passage be uniquely connected with washroom, the hydraulic pressure current backflow preventing high building draining from producing can be played, the foul smell caused draws water and goes out the situation of toilet, because the blocking of return flume incrustation scale generation or dunghill are on the impact of environment of toilet simultaneously after can preventing using toilet for a long time.

Float ball is controlled by drain button, coordinates Negative pressure machine float ball to be pulled open, realize draining after pressing drain button, after draining terminates, is subject to water impact, by float ball refunds toilet mouth, again closes.

Accompanying drawing explanation

Fig. 1 is water closet lateral view;

Fig. 2 is top view.

Detailed description of the invention

As shown in Figure 1, float ball 1 20mm to 35mm larger than the water closet mouth of pipe 2, when pressing drain button 9, current rotate around the mouth of a river 7 and inject water closet 6, button 9 inside starts rotating shaft simultaneously, float ball 1 is pulled by drag hook 3, the return flume 5 of alternative U-shaped pipeline is allowed to carry out current discharge, button 9 bottom discharges water subsequently, float ball is rushed at the mouth of pipe 2 of water closet 6 by drag hook 3, as shown in Figure 2 simultaneously, Negative pressure machine 11 starts to start, Negative pressure machine 11 plays a part to pull float ball 1, produce gyration airflow simultaneously, start to produce air current flow around the mouth of a river under cushion 8 is fixing, the gas channel of flowing is also rich mouth of a river passage, the foul smell produced during excretion can be sucked rich mouth of a river passage by negative pressure, then air-flow is derived by ventilation lumen 10, water tank 12 is between button 9 and closet seat cushion 8, play spiral to wash away, and the effect of refunds float ball.Button 9 is a kind of horizontal stripe structures.Water closet sewer 4 is the anti-backwater structures of a kind of high pin, can prevent high building hydraulic pressure or air pressure and the dirt backflow that produces.
