Technical Field

The utility model belongs to the technical field of the air conditioner technique and specifically relates to an indoor set of air conditioning with multistage filtration is related to.

Background

The indoor machine of the air conditioner sucks indoor air into the interior, heats or cools the sucked air through the heat exchanger to dehumidify the air, and blows the air out of the room through the fan to adjust the temperature of the indoor air so as to dehumidify or heat the indoor air. The top of the current indoor air conditioner is provided with an air suction window, and the air inlet in the indoor air conditioner is provided with a catcher (actually a filter screen) to prevent the air channel in the heat exchanger from being blocked and ensure the smooth flow of the air channel. However, as the service time of the air conditioner increases, firstly, the accumulated dust on the trap increases, and particularly, under the environment with poor air quality, the cleaning times and the cleaning difficulty of the trap need to be increased, and the cover needs to be opened to draw out the filter element net during cleaning at every time, so that the cleaning is troublesome, labor and time are wasted, and if the trap is not cleaned in time, the air quality is reduced, and the use effect of the air conditioner is influenced. Secondly, the existing dust catcher has poor effect of intercepting and adsorbing bacteria and viruses in the air.

SUMMERY OF THE UTILITY MODEL

To the problem that air filter existed among the above-mentioned prior art air conditioning indoor set, the utility model provides a both can improve the filtration quality, the reducible cleaning number of times's air conditioning indoor set that has multistage filtration again.

The to-be-solved technical problem of the utility model is that: the utility model provides an air conditioning indoor unit with multistage filtration includes interior box and outer box, the outer box has panel and backplate, and the top between panel and the backplate is provided with rectangular window of induced drafting, interior box has inner panel and baffle, upper portion is provided with the trap between inner panel and the baffle, be provided with radiating fin in the interior box, be provided with the air current pipe on the radiating fin, be provided with the air outlet at interior box lower extreme, be provided with air supply fan in the radiating fin lower part, interior box lower extreme is provided with rotatable upper and lower aviation baffle, be provided with air cleaner in the window of induced drafting, air cleaner comprises a plurality of filtration monomers, it includes the transversal frame of personally submitting L shape, presses the frame and passes through the organic fiber filter screen of adhesive fixation between frame and pressure frame to filter the monomer.

The filtering single bodies are movably combined to form the air filter, the filtering single bodies are preferably formed by adopting fixed combination, when the filtering single bodies are formed into a whole by adopting the fixed combination, the connecting plates are integrally arranged on one side of the adjacent frames at intervals, pin holes are formed in the connecting plates, the upper plane of each connecting plate is lower than that of each frame, a connecting pin matched with the pin holes is arranged on one side of the other adjacent frame, and the fixed combination and the disassembly of the frames are realized by the matching of the connecting pins and the pin holes.

The utility model discloses under the structure that does not change current air conditioning indoor set, on current indoor set is with trap as one-level filtration basis, utilize the window of induced drafting at current air conditioning indoor set top, it makes with organic fiber filtering material to set up in the window of induced drafting, abluent air cleaner (HEPA filter screen) of being convenient for, indoor set during operation, can filter and intercept and adsorb bacterium and virus with the air that contains the dust particle more than 0.3 micron, therefore can alleviate the filter pressure of current indoor set built-in trap greatly, reduce the washing number of times of trap, improve filtration purification quality. The utility model discloses air cleaner in the window that induced drafts on also can be used to central air conditioning.
