Central air conditioner fan coil pipe air opening filtering device

Abstract

The invention discloses a central air conditioner fan coil pipe air opening filtering device. The central air conditioner fan coil pipe air opening filtering device comprises an angle iron frame, a filter shell, a filter and a dismounting rod. The angle iron frame is fixed to a roof and located on the outer side of an air duct air outlet. The filter shell is connected with the angle iron frame in a clamped mode. The filter is arranged in the filter shell. The filter shell is provided with a ventilation cavity and two functional cavities. The top and bottom of the ventilation cavity are provided with an air inlet and an air outlet correspondingly. Air flow of the air duct air outlet enters the filter through the air inlet and is then discharged from the air outlet. A positioning block, a first spring, a hinging seat, a first pawl, an inner sleeve, a fixing seat, an unlocking block, a locking mechanism, an unlocking mechanism and an air bag lever mechanism are arranged in each functional cavity. The filtering device is additionally arranged at the air flue air outlet, so that air blown out of a fan coil pipe can be filtered; and when air is not circulated because an air duct is blocked, the pressure of the air duct is increased, the position of a baffle and the position of a sliding block are changed due to expansion of an air bag, whether the air duct is blocked or not can be judged by observing the position of the sliding block or baffle, and therefore the filter can be cleaned in time.

Description

technical field [0001] The invention relates to the field of central air-conditioning accessories, in particular to a central air-conditioning fan coil tuyere filter device. Background technique [0002] With the development of urban construction and the improvement of people's living standards, the use of air conditioners is becoming more and more common. In some densely populated areas, central air conditioning systems are usually used for unified cooling and heating. Central air conditioning units pass refrigerant or heat medium into each There is a fan coil unit in each room, and the fan coil unit blows cold or hot air out after heat exchange. [0003] Due to the long-term temperature environment in the air duct, it is easy to survive a large number of bacteria. The existing fan coil unit does not have the function of air filtration, resulting in poor air quality and heavy odor, which is not conducive to people's health. For densely populated areas, especially In hospit...

Problems solved by technology

[0003] Due to the long-term temperature environment in the air duct, it is easy to survive a large number of bacteria. The existing fan coil unit does not have the function of air filtration, resulting in poor air quality and heavy odor, which is not conducive to people's health. For densely populated areas, especially In hospitals, the dirty air seriously affects people's health, and dust is easy to accumulate in the air duct, which leads to blockage of the air outlet and reduces the exhaust air volume. The staff cannot directly visually detect whether the air duct is blocked, so they cannot clean it in time
