Description

CENTRALIZED EXHAUST SYSTEM FOR BATHROOM SPACE OF
MULTI-STORY BUILDING
TECHNICAL FIELD
[DI] The present invention belongs to the technical field of heating and ventilation, and particularly relates to a centralized exhaust system for bathroom space of a multi-story building.
BACKGROUND ART
[02] Incessant renewal and iteration of multi-story building design leads to inclusion of comfort and environmental protection in the design requirements, and more focus on the quality of residential environment of housing. Bathroom space 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 bathroom space is a key point during ventilation design of residential and hotel buildings since its pollution has a considerable impact on the indoor environment of the buildings.
[03] Current ventilation of the bathroom space is basically implemented with exhaust fans mounted at ceilings in the middle and upper part of the bathroom space, and have at least the following defects based on existing design:
[04] the exhaust fans are usually mounted in the ceilings with consideration of aesthetic sense, to this end, the ceilings need to be sufficiently high to facilitate ventilation and heat dissipation of various electrical appliances, resulting in smaller story heights of the bathroom space as well as cramped space.
[05] In addition, existing exhaust requires openings, directly connected to the outdoor ordinarily, on walls, which permits potential entrance of rats, insects and birds even if gauze nets are arranged, and poses a potential safety hazard.
[06] Finally, the exhaust fans mounted at the ceilings cannot quickly discharge aerosol pollution generated by users in the toilets. The aerosol in the bathroom space can spread to other indoor space, or other stories through exhaust outlets, increasing the risk of cross-contamination.
[07] To this end, it is necessary to design a ventilation system to overcome the above technical defects.
SUMMARY
08] In order to solve the shortcomings in the prior art, the technical problem to be solved by the present invention is about how to provide a centralized exhaust system for bathroom space of a multi-story building, so as to achieve building-style centralized exhaust treatment, and avoid polluted air output through isolation from the outside.
[09] A technical solution used by the present invention for solving the technical problems above is as below:
[10] a centralized exhaust system for bathroom space of a multi-story building includes, from the aspect of key technology, a centralized exhaust pipe, where the centralized exhaust pipe is mounted on a wall of bathroom space of an M-story building, and a total length of the centralized exhaust pipe is not less than a height of a corresponding M-1-story building; and a bottom of the centralized exhaust pipe is sealed, and a top of the centralized exhaust pipe is connected to a master exhaust fan;
[11] the centralized exhaust pipe is provided with M exhaust outlets, the M exhaust outlets in the centralized exhaust pipe are all connected to story exhaust ducts, the exhaust outlets are in communication with the story exhaust ducts, exhaust outlets of the story exhaust ducts face the top of the centralized exhaust pipe, and air inlets of the story exhaust ducts are connected to corresponding exhaust outlets; and
[12] outer sides of pipe walls of the M exhaust outlets are each connected to a story connection pipe, and a front exhaust end of each story connection pipe is divided into a bath exhaust branch pipe and a toilet exhaust branch pipe; a nozzle of the bath exhaust branch pipe extends into a bath area of bathroom space of a corresponding story; and a nozzle of the toilet exhaust branch pipe extends into a toilet area of the bathroom space of the corresponding story.
[13] M is an integer greater than 2.
[14] Through the above design, the centralized exhaust pipe is arranged, and by arranging the bath exhaust branch pipe and the toilet exhaust branch pipe on each story, the bathroom space under the same projection of the whole building may be exhausted when the master exhaust fan starts exhaust, such that the whole communicating pipeline is in a negative pressure state of upward suction, centralized exhaust is achieved, building control is facilitated, intelligent design of the building is improved, and the pipeline is directly arranged in the wall or along the wall to avoid openings, in communication with the outside in the wall and achieve isolation from the outside.
And airflow formed by exhaust may increase air flowing in the bathroom space and achieve air exchange.
[15] Further, the story exhaust duct includes a transition pipe section far away from the exhaust outlet and an exhaust pipe section close to the exhaust outlet; an end of the transition pipe section of the story exhaust duct is sealed with an inclined plate,
[16] 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;
[17] the air inlet also acts as the exhaust outlet;
[18] 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; and 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 diameter smaller than that of the centralized exhaust pipe.
[19] By using the above solution, in order to prevent the story exhaust duct from causing too much resistance to airflow in the centralized exhaust pipe, when the story exhaust duct is designed for the centralized exhaust pipe, fluid transition design is used to effectively reduce obstruction to airflow. [BO] Further, a one-way valve is arranged in the exhaust pipe section of the story exhaust duct.
[21] By using the above solution, the one-way valve effectively avoids airflow interaction, and airflow may merely be output in one direction. Further, the centralized exhaust pipe and the M story exhaust ducts are integrally formed. By using the above solution, integrated forming is conducive to mounting.
[22] Further, a toilet air inlet end of the toilet exhaust branch pipe on each story is provided with an aerosol detection sensor and a second thermal infrared human body sensor; a bath air inlet end of the bath exhaust branch pipe on each story is provided with a first thermal infrared human body sensor; and a rear exhaust end of each story connection pipe is provided with a story exhaust fan; and

[24] By using the above solution, when odor is detected in the toilet area or there is a person in the toilet, the microprocessor quickly starts the story exhaust fan, increases an exhaust speed on the basis of original exhaust, accelerates odor discharge in the toilet area, avoids backflow and odor cross-transmission, and stops the story exhaust fan once the odor is removed through real-time monitoring.
[25] When someone enters the bath area, and the thermal infrared human body sensor detects that human enters, and defaults to bathing, such that the story exhaust fan is started to accelerate discharge of steam fog in the bath area. After the person leaves, the story exhaust fan stops automatically.
[26] On each story, the microprocessor may be selectively arranged to increase ventilation of the bathroom space of the story. And the microprocessor of the present invention has a clock function.
[27] Further, an ultraviolet sterilizer is arranged 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, and an air duct is formed among all the ultraviolet lamps; and 28] the ultraviolet lamp is connected with a sterilization control end of the microprocessor.
[29] 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.
[30] Further, the toilet exhaust branch pipe is further internally provided with a first exhaust valve;
[31] the bath exhaust branch pipe is further internally provided with a second exhaust valve; and
[32] the first exhaust valve is connected with a toilet area exhaust control end of the microprocessor, and the second exhaust valve is connected with a bath area exhaust 5 control end of the microprocessor.
[33] By using the above solution, since the story exhaust fan is used for exhaust from two branch pipes, when exhaust of any one area needs to be strengthened, an exhaust valve on a branch pipe of the other area may be closed to accelerate exhaust.
[34] The present invention has the following technical effects:
[35] by using centralized exhaust design, the centralized exhaust pipe is mounted on the building, and extends into the toilet area and the bath area in the bathroom space by means of the branch pipes. The master exhaust fan is arranged at the end of the centralized exhaust pipe to achieve overall exhaust. In addition, airflow is formed indoors, such that indoor air exchange is accelerated, inflow of fresh air into the room is accelerated, and the odor is removed. When there is odor in the toilet area and bath in the bath area, exhaust may be strengthened.
