INDOOR UNIT OF AIR CONDITIONER Russian patent published in 2019 - IPC F24F13/20 

FIELD: ventilation and air conditioning.

SUBSTANCE: present invention relates to an air conditioner inner block having an air outlet formed only on the lower surface of the casing. Inner unit comprises box-type casing with air inlet on casing upper surface and air outlet on casing bottom surface; air supply device, located in housing, wherein the air supply device is configured to suck air of the room through the air inlet port and supply the conditioned air through the air outlet; a heat exchanger disposed in the housing, wherein the heat exchanger is configured to forcibly heat exchange the room air with the refrigerant for feeding the conditioned air; vertical deflector, first auxiliary vertical deflector and second auxiliary vertical deflector, each of which is located with possibility of rotation in the air outlet and is configured to change the direction of the air flow in the vertical direction, at that, the second auxiliary vertical deflector includes a support and a guide, which is supported with possibility of rotation on the end, and located on the other end of the support, and passing perpendicularly to the support in side view, wherein during the cooling process the first auxiliary vertical deflector is located on the side of the front surface of the casing, the back end of the first auxiliary vertical deflector is located under the lower surface of the casing, second auxiliary vertical deflector is located under the first auxiliary vertical deflector, and the upstream end of the second auxiliary vertical deflector is located above the vertical deflector, wherein during the cooling process the guide of the second auxiliary vertical deflector is located under the first auxiliary vertical deflector, and the upstream end of the guide is located above the vertical deflector.

EFFECT: this allows supplying air in the forward direction and reducing or preventing condensation at the casing front section.
