Description

Central air conditioner ventilation filtering self-cleaning dust-removing sterilizing system
Technical Field
The invention particularly relates to a central air conditioner ventilation filtering self-cleaning dust-removing sterilization system.
Background
The ventilation system of traditional central air conditioner usually adopts the filter screen board to carry out filtration to ventilation system's air supply, and when central air conditioner's ventilation system worked, the filter screen board was caught particles such as dust at first to carry out filtration to the air inlet. The captured dust is mostly collected on the windward side of the filter screen plate. As the running time of the air conditioning unit is accumulated, the filter screen plate starts to be blocked, the resistance to the air flow is gradually increased, the energy consumption is gradually increased, and when the resistance is increased to a certain critical value, the filter screen plate needs to be cleaned or replaced for maintenance. When the filter screen plate cannot effectively work, the filter screen plate needs to be cleaned or replaced manually in time, and from the economic aspect, the labor cost and the consumable replacement cost during maintenance are very expensive.
The invention patent number 201610283052.3 discloses a smooth automatic cleaning and filtering device, which is characterized in that in order to reduce the manual cleaning strength and cleaning efficiency, a suction nozzle is utilized to drive a dust suction air pipe to slide left and right on the surface of a filter through a threaded screw rod and a sliding rod, then a high-pressure fan is used for exhausting air, dust on the surface of the filter is extracted, and the extracted dust is concentrated in a dust collection box; the suction nozzle drives the left and right sliding of the dust suction air pipe to be realized by driving the threaded screw rod to rotate through the gear motor, the speed of the left and right sliding is controlled by the speed reducer, the left and right sliding amplitude is controlled by the time, and the working time of the whole automatic cleaning and filtering device is controlled by the resistance of dust on the filter, so that the labor cost is saved, the repeated cleaning is realized, the material is saved, the energy source is saved, and the efficiency is improved.
However, even though the surface of the filter can be subjected to dust removal treatment by mechanical automation, in some specific devices or because the surface area of the filter is too large, the dust removal effect cannot meet the standard in practice, dust removal is easy to be insufficient and thorough, the dust removal and sterilization efficiency and cleanliness still have problems, and meanwhile, the operation mode still needs manual control, namely, a user is required to judge whether to perform operation dust removal or not under the condition that the user finds the air output of the device.
