The humidifying unit 30 is used to humidify the air blown from the air blowing unit 10 to obtain humidified air.
The purifying unit 40 is used to purify the air blown from the air blowing unit 10 to obtain purified air.
The control unit 60 controls the opening and closing of the air supply unit 10, the humidification unit 30, and the purification unit 40 according to the operating state of the central humidification system.
The central humidification system has a humidification mode and a self-cleaning mode.
When the central humidification system is in the humidification mode, referring to fig. 2, the humidification unit 30 and the purification unit 40 are both opened, the air blown by the air supply unit 10 passes through the humidification unit 30 and the purification unit 40 to obtain wet and clean air, and the wet and clean air flows into the room through the air duct main body 21 and the air supply air duct branch 22 to adjust the humidity in the room.
When the central humidification system is in the self-cleaning mode, referring to fig. 3, the purification unit 40 is turned on, the air blown by the air supply unit 10 obtains clean air through the purification unit 40, the clean air flows to the outside through the air duct main body 21 and the self-cleaning air duct branch 23 or returns to the air supply unit 10 to participate in the next air duct circulation, and the air duct main body 21 is cleaned and sterilized by the purified air, so that the air cleanliness is improved.

Further, when the central humidification system is set to be in the humidification mode, the working power of the purification unit 40 is set to be P1; when the central humidification system is in the self-cleaning mode, the working power of the purification unit 40 is P2; p1 < P2.
That is, the power of the purifying unit 40 is adjustable, and the purifying unit 40 operates at low power in the humidifying mode, so that the stimulation and side effects to the human body can be avoided while the purifying effect of the humidifying air is ensured; the purifying unit 40 is operated at high power in the self-cleaning mode to enhance the purifying effect, and the purifying effect of the air duct main body 21 is improved in a short time using the strongly purified air.
The self-cleaning air duct branch 23 preferably returns to the air supply unit 10, so that in the self-cleaning mode, the strongly purified air also circulates through the humidifying unit 30, and a certain sterilization effect is also exerted on the humidifying unit 30.
Further, referring to fig. 4, the self-cleaning mode has a first self-cleaning phase and a second self-cleaning phase; when the central humidification system is in the first self-cleaning stage, the purification unit 40 is started, and the air supply unit 10 operates for T1 time at the air speed V1; when the central humidification system is in the second self-cleaning stage, the purification unit 40 is closed, and the air supply unit 10 operates for T2 time at the wind speed V2; wherein V1 is less than V2, and T1 is more than T2.
In the first self-cleaning stage, the air supply unit 10 operates at a low wind speed, so that the purified air obtained by the purification unit 40 can stay in the air duct main body 21 for a long time, and the inside of the air duct main body 21 can be sterilized and disinfected within a sufficient time, thereby preventing the influence of the too fast wind speed on the sterilization effect.
In the second self-cleaning stage, the air supply unit 10 operates at a high-grade air speed to effectively blow off the residual substances in the system, prevent the bacteria from breeding again in a humid environment, improve the purification effect, and simultaneously avoid the residual substances from entering the room in a humidification mode to generate peculiar smell or generate irritant influence on the human body.
In the second self-cleaning stage, the air supply unit 10 is automatically turned off after running for T2 time on the high-speed windshield, thereby improving the intelligent automation of the system.
As a preferable example, T1 is 3-10min, and can be adjusted by actual system design and purification effect, and too short affects self-cleaning effect, and too long affects user experience; t2 is 10-90s, can design and the effect of drying by the wind by the actual system is confirmed, and the effect of drying is influenced to the overlength, influences user experience.
Further, referring to fig. 2 and 3, each air supply duct branch 22 is provided with a humidifying valve 70, the self-cleaning air duct branch 23 is provided with a self-cleaning return air valve 80, and the control unit 60 controls the opening and closing of the humidifying valve 70 and the self-cleaning return air valve 80; when the central humidification system is in the humidification mode, the humidification valve 70 is opened, and the self-cleaning return air valve 80 is closed, so that wind blown out by the air supply unit 10 can enter the room through the air supply duct branch 22 and is prevented from entering the self-cleaning duct branch 23; when the central humidification system is in the self-cleaning mode, the humidification valve 70 is closed, and the self-cleaning return valve 80 is opened, so that wind blown out by the air supply unit 10 can circulate through the self-cleaning air duct branch 23, and the wind is prevented from entering the room through the air supply air duct branch 22.
The control unit 60 adjusts the opening or closing of the corresponding humidification valve 70 according to the humidity conditions in each room to achieve independent adjustment of the humidity of each room.
The central humidification system automatically enters a self-cleaning mode after running for a certain time in the humidification mode so as to automatically and periodically clean and sterilize the pipeline.
As a preferred embodiment, the humidifying unit 30 includes a water tank 50 and a water inlet pipe 51 communicated with the water tank 50, the water inlet pipe 51 is provided with a water inlet valve 52, the control unit 60 controls the opening and closing of the water inlet valve 52, and when the water in the water tank 50 is insufficient, the water inlet valve 52 is opened to replenish water into the water tank 50 in time; when the water in the water tank 50 reaches a set level, the inlet valve 52 is closed.
The purifying unit 40 can adopt a purifying technology common in the prior art, for example, an electrolytic water-soluble bacteria purifying technology, water in the water tank 50 is changed into bacteria-dissolving ionized water with strong oxidizability through the electrolytic water technology, and the oxidizability of the bacteria-dissolving ionized water is utilized to realize sterilization and disinfection; the water in the water tank 50 can be changed into the charged water mist ionized water by adopting a water mist ion purification technology and high-voltage corona discharge, and the sterilization and disinfection can be realized by utilizing the strong oxidizing property of the water mist ions.
The humidifying unit 30 can adopt a conventional humidifying technology, for example, a humidifying membrane is humidified by water in the water tank 50, and when the wind blown by the wind supply unit 10 passes through the humidified membrane, the moisture on the humidified membrane is taken away, so as to form humidified air; the water in the water tank 50 can be evaporated to form water vapor by adopting a water mist evaporation technology, and when the air blown out by the air supply unit 10 passes through the upper part of the water tank 50, the water vapor is taken away, so that humid air is formed.
The present embodiment is not particularly limited to the humidification unit 30 and the purification unit 40, and can be applied to the present embodiment as long as humidification and purification of air can be achieved.
It should be noted that, when the central humidification system is in the self-cleaning mode, some purification technologies need to be matched with a certain humidity to obtain an ideal purification effect, in this case, the humidification unit 30 and the purification unit 40 can be simultaneously turned on in the first self-cleaning stage to achieve a better purification effect.
In the foregoing description of embodiments, the particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
