Embodiment 1

[0028] Such as Figure 1-11 As shown, an indoor unit of an air conditioner with the function of automatically cleaning the filter screen is provided with an air filter 1 along the air path from the air inlet on the front upper part of the indoor unit of the air conditioner and the upper part to the exhaust port on the front lower part. , heat exchanger 2 and blower fan 3; The air conditioner indoor unit also includes a reciprocating filter cleaning device that can make the air filter screen reciprocate and clean the filter screen; the filter screen cleaning device It includes a dust absorption box 4 with an inlet and an outlet, the inlet is connected to a duckbill-shaped suction nozzle 5, the outlet is connected to a hose 6 for suction, and the suction hose 6 is connected to A dust suction box 7 that accommodates a centrifugal fan is also connected with a pipeline extending to the outside of the indoor unit housing on the dust suction box 7; A gear 42, the gear 42 meshes with...

Embodiment 2

[0034] The difference between this embodiment and Embodiment 1 is that the dust suction box 7 is omitted in this embodiment, and the centrifugal fan located in the dust suction box is arranged in the dust suction box 4, so that the entire cleaning device The volume is further reduced. In this way, the structure of the filter screen cleaning device becomes: the filter screen cleaning device includes a casing containing a fan and an inlet and an outlet, the inlet is connected to a duckbill-shaped suction nozzle, and the outlet and A hose extending to the outside of the indoor unit is connected; a gear driven by a motor is also installed outside the box, and the gear is engaged with a rack provided on the housing of the air conditioner indoor unit.

Abstract

The indoor unit of air conditioner with automobile air strainer cleaning function has one air strainer, one heat exchanger and one blowing fan set between the air passage between the air inlet and theair outlet. It has also one rotating set for reciprocating air strainer and one air strainer cleaning reciprocator, which includes one dust absorbing case with one inlet and one outlet, one sucking nozzle connected to the inlet, one hose connected to the outlet, one pipe connected to the dust absorbing case and stretching beyond the casing of the indoor unit, one gear driven onto the dust absorbing case, and one gear rack meshed to the gear.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an indoor unit of an air conditioner with the function of automatically cleaning the filter screen. Background technique [0002] In order to prevent dust from adhering to the heat exchanger and affecting the heat exchange effect, the indoor unit of the existing air conditioner is provided with a filter on the rear side of the air inlet of the indoor unit; after a period of operation Finally, a thick layer of dust will accumulate on the surface of the filter screen; if the filter screen is removed from the indoor unit of the air conditioner for cleaning in time, then installed and reused, the heat exchanger can be protected without affecting the heat transfer. effect; yet the existing air conditioner indoor unit is usually installed in the height of the room, and it is not a very convenient thing for people to remove and wash the filter screen; so the filter screen gener...
