Central air conditioner fan coil air outlet filtering device convenient to disassemble and assemble

Abstract

The invention discloses a central air conditioner fan coil air outlet filtering device convenient to disassemble and assemble. The filtering device comprises a fixing frame fixed on a wall and positioned on the outer side of an air outlet of an air duct, trapezoid frames detachably arranged in the fixing frame, a filter frame fixed on a position between the trapezoid frames, a filter arranged in the filter frame and corresponding to the air outlet of the air duct, and a disassembling and assembling rod mechanism for disassembling and assembling the trapezoid frames; air blown out through the air outlet of the air duct in a horizontal motion is blown out after passing through the filter; and two limiting mechanisms for clamping the trapezoidal frames are symmetrically arranged in the fixing frame. According to the filtering device, due to the fact that the filtering device is additionally arranged at the air outlet of a vertical surface of the wall, the air blown by a fan coil can be filtered to remove odor, dust and harmful gas, and therefore breathing health of people is guaranteed; and the filtering device is convenient to disassemble and assemble, the trapezoidal frames can be quickly assembled and disassembled through the disassembling and assembling rod, and the filter can be taken out for cleaning, and the filtering device is simple to operate and high in practicability.

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 which is easy to assemble and disassemble. 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 dens...

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 will block the air outlet and reduce the exhaust air volume. To solve this problem, a filter device can be installed at the air outlet of the air duct, but how to install it Filtering device, so that it has a good filtering effect, and at the same time, it is easy to disassemble and clean the filter, which is a problem that technical personnel need to solve at present.
