Description

CENTRALIZED EXHAUST SYSTEM FOR PUBLIC TOILET
TECHNICAL FIELD
[01] The present invention belongs to the technical field of building heating and ventilation design, and particularly relates to a centralized exhaust system for a public toilet.
BACKGROUND ART
[02] In recent years, “toilet revolution” has been vigorously advocated in China accompanied by attention paid to improvement of the quality of human settlements. A toilet is the primary origin of indoor aerosol and other pollutants, as well as a key site where cross-infection is caused by long-distance aerosol transmission and contact transmission of some infectious diseases. By convention, the toilet is a key point during ventilation design of buildings since its pollution has a considerable impact on the indoor environment of the buildings. The public toilet is currently ventilated with exhaust fans mounted at ceilings in the middle and upper part of public toilet by and large. In existing ventilation design and system of the public toilet, less attention is paid to creation of a healthy and comfortable air environment, which probably leads to aerosol pollution (odor) pervading the whole toilet and even adjacent space.
[03] Specifically, based on existing ventilation design of the public toilet, the exhaust fans are mounted at the ceiling of the toilet to discharge bio-aerosol pollutants and odor generated during use.
[04] However, the above design has the following defects:
[05] Since the public toilet has a great designed story height, and the exhaust fans are mounted at high places, exhaust fans with high power are required by basic demand for air supply and exhaust, causing much noise. Besides, the exhaust fans are arranged at the tops, limiting an exhaust area to the top area of the toilet, and resulting in forming of a small range of local airflow indoors, poor ventilation and exhaust effects, and difficulty in quickly discharging the bio-aerosol pollutants and odor generated during use.
[06] In addition, partitions are often used to divide the public toilet into a plurality of cubicles, and lots of airflow blind areas are formed inevitably on account of airflow shielding by baffles. However, the cubicles are the main places of pollution and odor generation in the public toilet. If one exhaust fan charges with exhaust of the plurality of cubicles, it takes a long time to remove odor, and subsequent users will be seriously affected in the case of frequently used public toilets.
SUMMARY
[07] In order to solve the above shortcomings of the prior art, the technical problems to be solved by the present invention is to rationally arrange and design a ventilation pipeline, reduce overall power consumption, achieve overall building exhaust of a public toilet, rapidly remove bio-aerosol pollutants and odor generated during use of the public toilet, accelerate odor removal in a cubicle, and reduce cross-contamination.
[08] A technical solution used by the present invention for solving the technical problems above is as below:
[09] a centralized exhaust system for a public toilet includes, from the aspect of key technology, a centralized exhaust pipe, where the centralized exhaust pipe is mounted on a wall of a public toilet in a building, a bottom of the centralized exhaust pipe is sealed, and a top of the centralized exhaust pipe is connected to a master exhaust fan;
[10] the centralized exhaust pipe is provided with M exhaust outlets correspondingly on the basis of the number of building stories, the M exhaust outlets in the centralized exhaust pipe are all provided with story exhaust ducts, a side wall of each story exhaust duct is further provided with an air inlet, and the air inlets of the story exhaust ducts are in communication with corresponding exhaust outlets; and outer sides of portions, corresponding to the M exhaust outlets, of a pipe wall of the centralized exhaust pipe are each connected to a story connection pipe, and each story connection pipe is connected to N toilet exhaust branch pipes, the N toilet exhaust branch pipes extending into N toilet partitions respectively. N and M are positive integers.
[11] Through the above design, the centralized exhaust pipe is mounted on the wall of the public toilet in the building, and then the master exhaust fan is combined to achieve the overall building exhaust treatment, instead of direct external ventilation, which effectively reduces the risk of cross-infection caused by the pollutants in the toilet. And the plurality of toilet exhaust branch pipes are combined to directly extend into each partition or cubicle in the public toilet, forming a plurality streams of airflow in the toilet, removing an airflow blind area, and accelerating the odor removal in the cubicle.
[12] According to a further technical solution, the story exhaust duct includes a transition pipe section at a front end of the air inlet and an exhaust pipe section at a rear end of the air inlet; an end of the transition pipe section of the story exhaust duct is sealed with an inclined plate; the exhaust pipe section of the story exhaust duct is arranged in a direction parallel to that in which the centralized exhaust pipe is arranged, and the story exhaust duct has a radial section area smaller than a half of a radial section area of the centralized exhaust pipe.
[13] By using the above design, in order to prevent the story exhaust pipe from causing too much resistance to airflow in the centralized exhaust pipe, when the story exhaust pipe is designed for the centralized exhaust pipe, fluid transition design is used to effectively reduce obstruction to airflow.
[14] Further, the story exhaust duct includes a story exhaust pipe, a pipe wall of the story exhaust pipe being axially provided with a via opening, and the via opening axially abutting on an inner pipe wall of the centralized exhaust pipe; the air inlet also acts as the exhaust outlet; and the end of the transition pipe section of the story exhaust duct is sealed with the inclined plate, a bottom end of the inclined plate abuts on a portion, corresponding to the via opening, of the inner wall of the centralized exhaust pipe, and a top end of the inclined plate abuts on a side wall, far away from the via opening, of the story exhaust pipe.
[15] By using the above solution, mounting design of the story exhaust duct is facilitated.
[16] Further, in order to facilitate construction and mounting and reduce construction difficulty, the centralized exhaust pipe and the M story exhaust ducts are integrally formed.
[17] Further, a one-way valve is arranged in the exhaust pipe section of the story exhaust duct.
[18] By using the above solution, the one-way valve effectively avoids airflow interaction between stories, and airflow may merely be output in one direction.
[19] Further, in order to achieve intelligent control, each public toilet in the building are provided with a microprocessor, a gas detection row of the microprocessor is connected to N aerosol gas sensors, and N person detection ends of the microprocessor are each connected with an infrared human body sensor, and the N aerosol gas sensors and the N infrared human body sensors are mounted at air inlets of the N toilet exhaust branch pipes in a one-to-one corresponding manner;
[20] a strong exhaust control end of the microprocessor is connected with a story exhaust fan; and the story exhaust fan is mounted in a portion, close to the exhaust outlet, of the toilet exhaust branch pipe.
[21] An approaching person may be detected by means of the infrared human body sensor, and the story exhaust fan may be started quickly. When the odor is detected, the started story exhaust fan accelerates odor discharge. Automatic detection is achieved, exhaust is automatically started and accelerated, and the degree of intelligence is improved.
[22] Further, an ultraviolet sterilizer is further mounted in the toilet exhaust branch pipe, ultraviolet lamps of the ultraviolet sterilizer are circumferentially arranged on an inner wall of the toilet exhaust branch pipe, an air duct is formed among all the ultraviolet lamps, and the ultraviolet lamps are connected with a sterilization control end of the microprocessor.
[23] By using the above solution, the ultraviolet sterilizer is formed by arranging the ultraviolet lamp string and mounting plates circularly, and the lamp string is circularly fixed on the inner wall of the toilet exhaust branch pipe by the circularly-arranged mounting plates, and the air duct is formed in the middle.
Ultraviolet sterilization is performed on flowing air. Pollution intensity of discharged air is effectively reduced.
[24] Further, one end, far away from the air inlet, of each toilet exhaust branch pipe is further provided with a strong exhaust control valve, and all the strong exhaust control valves are connected with the strong exhaust control end of the microprocessor. [BS] By using the above solution, in order to accelerate an exhaust speed of a certain area, exhaust of other branch pipes in the same story may be closed, so as to strengthen the negative pressure exhaust intensity and accelerate the exhaust speed in the area.
[26] The present invention has the following technical effects:
[27] By using centralized exhaust design, the centralized exhaust pipe is mounted on the building, and extends into each air flow blind area in the public toilet through branch pipes. By combining an original blower in the toilet, a plurality of steams of 5 airflow in a plurality of places are formed, thereby effectively removing the airflow blind area, accelerating odor removal in the cubicle and reducing cross-contamination.
In addition, an intelligent exhaust strengthening control system is designed to monitor and control exhaust in real time.
