Abstract
The utility model relates to a bathroom drainage and a vent system that solves the problem of drainage and odor venting inside bathrooms The device comprises a main drainage pipeline that connects the main pipe of the sewage system and a multitude of branch drainage pipes that connect the main drainage pipe, and the other end of the branch drainage pipe is joined with the sewage outlet of the toilet bowl. Its characteristics are that a check valve is provided between the main drainage pipe and the drainage system, check valves are provided between the branch drainage pipe and the toilet bowl and an air outlet is provided atop the main drainage pipe. Due to the adoption check valves provided between the branch drainage pipes and the toilet bowl, no return current will be generated when the bowl is flushed. Since only a small amount of water is needed to flush clean the toilet bowl, it features substantial water-saving effects; in addition, the setup of check valves also blocks the return of odor from the sewage system so that odor in the bathroom is avoided. And because the air outlet atop the main drainage pipe integrates the functions of air venting and drainage, the device features simple, convenient and rational structures.
Description
Technical field
The utility model relates to a kind of drainage system, specifically is the drainage system of a kind of building washroom exhaust simultaneously.
Background technology
At present various water closets, the pan that uses in the washroom causes the washroom that peculiar smell is arranged easily simultaneously, convenient after immediately water dash, otherwise it just at the closet internal memory, and is extremely unhygienic; Because what closet adopted is to return water-bound, water has lacked towards unclean, and it is just passable to need a large amount of water to dash, and causes the waste of water resource, and stops up easily, brings a lot of inconvenience to life.
Summary of the invention
In order to solve the shortcoming that above-mentioned prior art exists, the purpose of this utility model provides a kind of building toilet drainage exhaust system, and it can keep not having in the washroom peculiar smell and using water wisely.
The technical solution of the utility model is: the toilet drainage exhaust system, comprise the main sewer pipe that connects sewer and be connected a plurality of sewer pipes on the main sewer pipe, the other end that props up sewer pipe connects the closet sewage draining exit, it is characterized in that: be provided with one way valve between main sewer pipe and the sewer, be equipped with one way valve between each sewer pipe and the closet, the top of main sewer pipe is provided with the gas outlet.
The beneficial effects of the utility model are: so it is not because employing can be returned water when being provided with one way valve flushing closet between a sewer pipe and closet, thus can toilet stool washing is clean with low amounts of water, water-saving result is obvious; And the smell that the setting of one way valve has also been blocked in the sewer returns flavor, avoids causing peculiar smell in the washroom; Because it is the gas outlet on main sewer pipe top makes it integrate exhaust, draining, simple in structure, convenient and reasonable again, be applicable to various buildings washroom.
Description of drawings
Accompanying drawing is a structural representation of the present utility model,
Among the figure: 1 one way valve, 2 main sewer pipes, 3 sewer pipes, 4 one way valves, 5 closets, 6 gas outlets, 7 sewers.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified,
As shown in drawings.
This toilet drainage exhaust system, comprise the main sewer pipe 2 that connects sewer and be connected on the main sewer pipe 2 two sewer pipes 3, the other end of two sewer pipes 3 connects closet 5 sewage draining exits in the two floor washrooms respectively, be provided with one way valve 1 between main sewer pipe 2 and the sewer 7, be equipped with one way valve 4 between each sewer pipe 3 and the closet 5, the top of main sewer pipe 2 is provided with gas outlet 6.
Usually under the state, the one way valve 4 of each floor all is in crack state, and the peculiar smell air-flow can continually pass through water closet 5, one way valve 4, a sewer pipe 3 from 6 discharges through the gas outlet of main sewer pipe 2 so when an opportunity arises; When upstairs flushing the toilet, form air-flow at main sewer pipe 2 and pour in down a chimney, the one way valve 4 in the ground floor is closed, thereby avoids air-flow to enter the washroom through water closet 5.
When flushing the toilet, water is through water closet 5, and one way valve 4 is opened, and arrives main sewer pipe 2 by a sewer pipe 3, and the one way valve 1 that final process is opened is discharged to sewage in the sewer 7; For the peculiar smell in the anti-sewer 76 is dispersed into contaminated environment in the ambient air through the gas outlet, one way valve 1 is in closed condition usually.So it is not because employing can be returned water when being provided with one way valve flushing closet between a sewer pipe and closet, thereby can toilet stool washing is clean with low amounts of water, water-saving result is obvious.
As other embodiments, can connect a plurality of sewer pipes on the main sewer pipe 2, so that be applied to the many buildings of floor.
