Description

Built-in air conditioner indoor unit with up-down air outlet Technical Field The invention relates to the technical field of air conditioning, in particular to an embedded air conditioner indoor unit with upper and lower air outlets. Background Along with the continuous improvement of the living standard of people, the embedded air conditioner can be perfectly integrated into the household environment, so that the embedded air conditioner gradually becomes a better choice for users. The existing built-in air conditioner is usually a cabinet built-in air conditioner, and needs to be built into a cabinet, which determines that only the front of the air conditioner body is exposed to the outside, thereby determining that the air inlet and outlet forms are forward and forward. However, the embedded air conditioner on the market at present generally only opens an air inlet below the front side of the indoor unit, opens an air outlet above the front side of the indoor unit, and only sets an evaporator between the air inlet and the air outlet at the position below the air outlet, which has the problem of lower heat exchange efficiency. In addition, the evaporator is obliquely arranged between the air inlet and the air outlet, the space utilization rate in the indoor unit of the air conditioner is low, the size of the fan is severely limited due to space extrusion, the air inlet efficiency and the air outlet efficiency are low, and the problem that the heat exchange efficiency of the embedded air conditioner is low is caused.
