Problems solved by technology

One disadvantage of this kind of air supply is that the air sent out is all heat exchange air, the air volume is small, and the indoor air circulation speed is slow; another disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air blown out The wind blows directly on the user, and the user feels uncomfortable
[0003] In addition, because the indoor units of the existing wall-mounted air conditioners are long strips, they are not only bulky and occupy a large installation space, but also not beautiful enough to meet the diverse needs of the market.

Embodiment Construction

[0045] figure 1 is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, figure 2 yes figure 1 The schematic cross-sectional view of the indoor unit of the air conditioner shown. Such as figure 1 and figure 2 As shown, the embodiment of the present invention provides an air conditioner indoor unit. The air conditioner indoor unit may include a housing 20 , a centrifugal fan 30 , a heat exchanger 40 and an air guiding device 50 . The housing 20 may have a first air inlet, a second air inlet and an air outlet. Preferably, the first air inlet can be located at the upper part of the housing 20, such as the upper front, the upper rear and / or the upper parts on both sides; the second air inlet can be arranged at the lower rear of the housing 20; the air outlet can be arranged at The lower front side of the housing. The centrifugal fan 30 may include an impeller 31 and a volute 32 , which are disposed in the cas...

Abstract

The invention provides an air conditioner indoor unit which comprises a shell, a centrifugal draught fan, a heat exchanger, a flow leading and air guiding device, and a shielding device. The shell is provided with a first air inlet, a second air inlet and an air outlet. The centrifugal draught fan is arranged in the shell and is configured to promote air flow to flow towards the air outlet from the first air inlet. The heat exchanger is arranged in the shell and is located in an air inlet area of the centrifugal draught fan. The flow leading and air guiding device is arranged in the shell and is configured to guide air flow from the centrifugal draught fan and air flow from the second air inlet into the shell for mixing, and therefore mixed air flow can be sent out from the air outlet. The shielding device is configured to open or close the second air inlet in a controlled manner. The air conditioner indoor unit is large in air sending amount, in addition, the flow mixing proportion of non-heat-exchange air and heat exchange air can be adjusted, and soft mixed air with a proper temperature can be blown out in a controlled manner.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, in particular to an air conditioning indoor unit. Background technique [0002] The indoor units of the existing wall-mounted air conditioners are all strip-shaped, and use a cross-flow fan and a bent evaporator for air supply. The indoor unit of the wall-mounted air conditioner is not only prone to appearance visual aesthetic fatigue, but also the wind after heat exchange of the bending evaporator is directly blown out from the air outlet under the action of the internal cross-flow fan, and all the blown air is heat exchange air. One disadvantage of this kind of air supply is that the air sent out is all heat exchange air, the air volume is small, and the indoor air circulation speed is slow; another disadvantage is that the air sent out is not soft enough, especially in the cooling mode, the cool air blown out The wind blows directly on the user, and the user feels uncomfortable.
