Mounting structure of air filter of cabinet air-conditioning indoor unit

Abstract

The invention discloses a mounting structure of an air filter of a cabinet air-conditioning indoor unit. The air filter is positioned at an airflow outlet above an indoor air supply turbofan. Because the air filter is placed at the outlet of the fan, the suction resistance of the fan is greatly reduced, and the flow is improved; the inlet space of the fan is increased so that the airflow is not accumulated in the inlet space of the fan and the noise is reduced; the airflow at the outlet of the fan nearly flows upwards vertically and is well matched with the crisscross structure of the air filter, so noise is not caused in the inlet space; and when a customer needs to clean the air filter, the filter can be extracted from the lateral surface.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an installation structure of an air filter of an indoor unit of a cabinet type air conditioner. Background technique [0002] Generally, an air conditioner is a machine for cooling or heating indoors and purifying indoor air by using a refrigeration cycle composed of a compressor, a condenser, an expansion component, and an evaporator in order to provide users with a comfortable environment. [0003] Existing cabinet air conditioner indoor units such as Figures 1 to 4 As shown, a body 50 constituting the exterior is included. The lower part of the main body 50 forms air suction ports 51, 52 for sucking indoor air. [0004] The air inlets 51 and 52 include a left side air inlet 51 provided on the lower left side of the main body 50 and a right side air inlet 52 provided on the lower right side of the main body 50 . [0005] The lower front of the main body 50 is also provided with a front ...

AI Technical Summary

Problems solved by technology

But the fan inlet is a very critical part, where the airflow is rotated and sucked in at a high speed, and the air filter occupies a large part of the already small space here, making the air flow area smaller and causing increased noise

Moreover, the wind is inhaled from the suction ports on both sides, which does not match the pore structure (crisscross) of the air filter and the rotating air flow, which causes the flow rate to drop.
