Description

Built-in air conditioner indoor unit with up-down air intake 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 inlets. Background In the trend of integration of home appliances, home appliances such as refrigerators and dish washers successfully realize embedded installation and perfectly integrate into home environments. As a large household appliance in a living room, the air conditioner also needs to conform to the trend, and the air conditioner cabinet can be 'hidden' in the household environment through the embedded design, so that the overall attractiveness is improved, and the requirements of modern families on simple and clean space can be better met. The integrated design not only optimizes space utilization, but also enhances harmony and comfort of the home. Because the other side surfaces except the front side surface of the embedded air conditioner are shielded by furniture and/or walls, in order to ensure the smoothness of the air inlet and the air outlet of the embedded air conditioner, the prior embedded air conditioner is generally provided with an air inlet and an air outlet at the front side at the same time. However, the embedded air conditioner in the market at present is usually only provided with an air inlet below the front side of the indoor unit, and is provided with an air outlet above the front side of the indoor unit, and the air inlet below the front side is easily shielded by sundries on furniture, carpets or floors, so that the air inlet is unsmooth, and the operation efficiency of the embedded air conditioner is affected. In addition, only one air inlet is formed below the air outlet, so that the air inlet flow caused by cold air sinking is easy to be more air with lower temperature after heat exchange when the refrigerating mode is operated, the air flow with lower temperature above the indoor part is difficult to enter the indoor unit, and the uniformity of the indoor temperature is seriously affected. Disclosure of Invention In view of the above, the present invention proposes an air conditioning indoor unit that overcomes or at least partially solves the above-mentioned problems.
