A self-cleaning ventilator for buildings and its working method

Abstract

The invention discloses a self-cleaning ventilator for buildings and its working method, which comprises a filter screen, a cleaning mechanism, a sound insulation board, a drain pipe and a controller. Compared with the prior art, the invention has a remarkable sound insulation and dust removal effect, especially for The cleaning of dust inside the ventilator is more efficient. The filter screen can effectively prevent dust from entering the room, and the excess dust will be blocked by the filter screen and fall to the sound insulation board. The inclined setting of the sound insulation board can prevent insects and birds from entering it to build nests. The mechanism cleans the dust inside the filter screen and ventilator in time to effectively prevent the secondary dust from polluting the indoor air. The outflow will not pollute the wall and affect the overall appearance. The ventilator can be artificially intervened through the module of the controller. The cleaning, maintenance, opening and closing are intelligent, the sound insulation effect is good, and it has strong practicability.

Description

technical field [0001] The invention relates to a self-cleaning ventilator for buildings and a working method thereof, belonging to the technical fields of environmental protection and purification, building components and intelligent control. Background technique [0002] With the improvement of people's living standards, people's requirements for indoor air quality are also constantly improving. The use of air conditioners can improve the indoor environment, but long-term use of air conditioners will lead to a decrease in indoor air quality and cause various "air-conditioning diseases". Therefore, it is necessary to improve indoor air quality through building ventilation equipment. Under normal circumstances, if a building needs to be ventilated, it needs to open the building's outer windows, and opening the building's outer windows for ventilation will bring a series of problems such as outdoor noise, dust, security and anti-theft.

AI Technical Summary

Problems solved by technology

Under normal circumstances, if a building needs to be ventilated, it needs to open the building's external windows, and opening the building's external windows for ventilation will bring a series of problems such as outdoor noise, dust, safety and anti-theft.

[0003] The existing ventilator structure has the following problems: ① During the ventilation process, it is difficult to eliminate the outdoor noise, so that the outdoor noise invades the room; ② The ventilator is usually in the open state in dusty and smoggy weather. The sand and dust spread to the room, affecting the indoor air quality; ③There is no rain-shielding structure, and the outdoor rainwater is easy to invade the ventilator; A large amount of fine dust accumulates on the inner surface of the gauze and ventilator, and the strong wind is likely to cause secondary dust pollution. Efficient automatic dust removal measures need to be developed
