Filter screen structure of indoor unit of low-static pressure type air-conditioner

Abstract

The invention relates to a filter screen structure of an indoor unit of a low-static pressure type air-conditioner, which is arranged on an air returning port at the air inlet side of the indoor unit for filtering dust and suspended matter in air. The filter screen structure comprises a filter screen and a frame, wherein a plurality of elastic clamping parts are arranged on the frame of the filter screen which is fixed on the air returning port of the indoor unit through the clamping parts. The fixed structure of the filter screen is arranged on the filter screen per se and has simplicity and easy realization so that material cost and labor cost required in production can be reduced; and when the filter screen of the indoor unit is installed, as long as the clamping parts are deformed, a shell of the indoor unit can be clamped by the filter screen, and overlarge operation space does not need to be occupied in the installation process so that the filter screen has more convenient installation and disassembly. Furthermore, a plurality of elastic contacts are fixed between the filter screen and the shell, and the filter screen is not easy to generate shifting and deformation in the using process of the air-conditioner, thereby ensuring the effects of filtration and dust removal of the filter screen when in use.

Description

technical field [0001] The invention relates to the technical field of indoor units of air conditioners, in particular to a low static pressure filter which is directly fixed on the air return port of the indoor unit by arranging clamping parts on the frame of the filter screen itself, thereby simplifying the assembly and disassembly process The filter structure of the indoor unit of the type air conditioner. Background technique [0002] An air conditioner is an indoor air temperature adjustment device, and its main components include a refrigeration cycle system including a compressor, a condenser, a throttling device, and an evaporator, and an air cycle system including a blower, an air duct, and an air inlet and outlet. The air conditioner absorbs indoor air, changes its temperature through the evaporator and condenser of the heat exchange device, and then discharges it back into the room to realize the functions of cooling or heating and dehumidification, so as to provi...

Problems solved by technology

[0014] The filter screen in the filter screen structure of the indoor unit of the low static pressure air conditioner in the prior art must be stretched and moved along the fixed direction set by the buckle during the process of disassembly and installation. When the installation space of the indoor unit is limited , the disassembly and assembly of the filter screen will be affected by the operating space, and the disassembly and assembly action is extremely inconvenient

On the other hand, in order to avoid deformation of the filter screen, the screws that fix the frame and the housing further increase the overall cost of the indoor unit, increasing the cost
