Description

An indoor ventilation system

technical field

The utility model relates to the field of exhaust systems, in particular to an indoor ventilation system.

Background technique

Statistics from the National Institute of Indoor Environmental Sciences and various monitoring departments show that the air pollution in large public places and residential buildings with a high population concentration in domestic cities is serious, with 70% seriously exceeding the standard, which has caused a large number of sick building syndromes ( Sick Building Syndrome), office syndrome, respiratory tract infection and cardiovascular diseases seriously affect people's health. The main sources of pollution include the following: first, waste gas discharged from human metabolism; second, various harmful substances such as aldehydes, benzene, and amines emitted from various decoration materials and furniture; third, various Bacteria, viruses, etc. In order to maintain the indoor environment, air purifiers or simple exhaust fans are installed in many rooms now, but air purifiers generally can only simply remove dust and kill bacteria, etc. It is difficult to absorb; while simple exhaust fans can only discharge part of the indoor air, but cannot completely remove the toxic and harmful gases in the room, especially when the indoor environment is relatively closed, the effect of ordinary exhaust fans is very poor.

Utility model content

In order to overcome the deficiency that the air purification system in the prior art cannot effectively remove bacteria, viruses and various harmful substances in the room, the utility model provides a method that can effectively discharge the harmful gas in the room to the outside, and at the same time ensure that there is no pollution in the room. Clean air supplements the indoor ventilation system to provide people with a good indoor environment.

In order to achieve the above object, the utility model adopts the following technical solutions:

An indoor ventilation system, including an air intake mechanism and an exhaust mechanism, the air intake mechanism includes a self-balancing air inlet installed above the window frame, and the self-balancing air inlet communicates indoor and outdoor, The exhaust mechanism includes an exhaust fan, the intake end of the exhaust fan is connected with a number of air intake pipes, the outer ends of the air intake pipes are respectively provided with air inlets, and the outlet end of the exhaust fan is connected with an exhaust pipe. The outer end of the exhaust pipe stretches out of the room, and the exhaust fan is also connected with a controller. Turn on the controller, and the controller controls the exhaust fan to work, thus forming a negative pressure in the relatively closed room. At this time, the self-balancing air inlet above the window frame is under the action of negative pressure, and the internal adjustment diaphragm can be adjusted according to the indoor load. The size of the pressure automatically adjusts the angle, thereby adjusting the cross-sectional area of the air intake. The air volume from the outside into the room remains constant, while the polluted air in the room enters the intake pipe from the air inlet and is discharged to the outside through the exhaust fan, thereby realizing indoor polluted air. The exchange with the clean air outside keeps the indoor air fresh and provides people with a good indoor air environment.

Preferably, a rainproof cover is provided directly above the self-balancing air intake above the outdoor window frame. The rainproof cover can effectively prevent rainwater from entering the self-balancing air intake.

Preferably, the exhaust fan is a self-balancing multi-point exhaust fan. The self-balancing multi-point exhaust fan has many advantages such as long-term continuous operation, low noise, can be connected with various ventilation pipes, and the exhaust air volume is constant. It is very suitable for the use of indoor ventilation systems.

Preferably, the air outlet is a self-balancing air outlet.

Preferably, a smoke alarm is provided at the air inlet. When the exhaust fan is working, the indoor air will enter the air inlet pipe from the air inlet. Therefore, when a small smoke is generated in the initial stage of a fire in the room, the smoke can be quickly sucked into the air inlet, and the smoke alarm at the air inlet It can call the police in the first time, thereby warning people that there is smoke in the room, and people may respond in a short time, which is safer.

Therefore, the utility model has the beneficial effect of being able to effectively discharge the indoor harmful gas to the outside, and at the same time ensure that the room is replenished with clean air, thereby providing people with a good indoor environment.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

Embodiment 1: An indoor ventilation system as shown in Figure 1 is installed in the same relatively sealed room, including an air intake mechanism and an exhaust mechanism. The air inlet 1, the self-balancing air inlet 1 is connected indoors and outdoors, and the rainproof cover 6 is fixed on the outdoor wall just above the right side of the self-balancing air inlet 1, and the exhaust mechanism includes an exhaust fan 2. This implementation The exhaust fan in the example is a self-balancing multi-point exhaust fan. The air intake end of the exhaust fan 2 is connected with four air intake pipes 3, and the outer ends of the air intake pipes 3 are respectively provided with air inlets 4. The air inlets in this embodiment are Self-balancing air inlets, the air inlets are installed in different positions in the same room, respectively on the walls of the four positions of upper left, lower left, upper right, and lower right, and each air inlet 4 is equipped with a smoke alarm 7, The outlet end of the exhaust fan 2 is connected with an exhaust pipe 5, and the outer end of the exhaust pipe 5 stretches out of the room, and the exhaust fan 2 is also connected with a controller. The controller controls the exhaust fan to work. When the exhaust fan is working, a negative pressure is formed in the relatively closed room, so that the regulating diaphragm in the self-balancing air inlet is opened, and the fresh air outside is discharged from the self-balancing air inlet. into the room, and the dirty air in the room enters the exhaust fan from the four air inlets, and then is discharged to the outside from the exhaust outlet, so as to realize the exchange of indoor and outdoor air, keep the indoor air fresh, and provide people with a good environment. The indoor air environment is beneficial to physical and mental health; at the same time, if a fire occurs indoors, the smoke sensor installed at the air inlet can quickly sense the smoke and then alarm to ensure people's safety.

Embodiment 2: An indoor ventilation system as shown in Figure 2, self-balancing air inlets 1 are respectively installed above the window frames of three relatively closed rooms, and self-balancing air inlets are located above the window frames outside the rooms. The rainproof cover 6 is respectively installed directly above the device 1, and the rainproof cover 6 can prevent outdoor rainwater from entering the room from the self-balancing air inlet 1, and the opposite sides of the self-balancing air inlet 1 in the three rooms Air inlets 4 are respectively installed on the wall or the suspended ceiling, and a smoke alarm 7 is installed on each air inlet 4. The air inlet in this embodiment is a self-balancing air inlet, and an exhaust fan 2 is installed in another room. In actual life, the room can be selected as a bathroom or a storage room. The exhaust fan in this embodiment is a self-balancing multi-point exhaust fan, and the air inlet of the air exhaust fan 2 is connected to three air inlets 4 through three air inlet pipes 3. , the outlet end of the exhaust fan 2 is connected with an exhaust pipe 5, the outer end of the exhaust pipe 5 stretches out of the room, and the exhaust fan 2 is also connected with a controller.
