Abstract

The invention discloses an air conditioner indoor unit. The air conditioner indoor unit comprises a base, a mounting shell, a back plate, a front panel, a lower volute fan assembly, an upper volute fan assembly and an evaporator assembly, wherein the base, the mounting shell, the back plate and the front panel define an accommodating space; the lower volute fan assembly is arranged inside the accommodating space and comprises a lower fan, a first volute and a second volute, and a lower air duct is defined between the first volute and the second volute; the upper volute fan assembly is arranged above the lower volute fan assembly and comprises an upper fan, a first upper volute and a second upper volute, and an upper air duct is defined between the first upper volute and the second upper volute; the evaporator assembly is arranged inside the accommodating space and is constructed in a mode that after the evaporator assembly exchanges heat with air entering the accommodating space from a return air inlet of the back plate, the air is guided respectively by the upper fan and the lower fan to enter the lower air duct and the upper air duct. The upward-downward air supply double cross-flow air conditioner indoor unit is high in heating efficiency and low in energy consumption and use costs.

Description

technical field

[0001] The invention relates to the field of air conditioner manufacturing, in particular to an indoor unit of a double cross-flow air conditioner with up and down air supply. Background technique

[0002] The motor wind wheel system of the indoor unit of the traditional floor-standing air conditioner is generally located at the bottom and supplies air upwards. The wind is blown out from the upper part of the indoor unit of the air conditioner through the evaporator and sent to the room. The circulating air can be guided obliquely downward to the lower space of the room through the air deflector. The air conditioner with this structure has a good cooling effect, but it does not affect the heating effect of the air conditioner. The reasons are: 1) First, the temperature The higher hot air moves upwards after being sent out of the air outlet, and it is difficult to use the wind deflector to guide the hot air obliquely downwards to a position very low from the g...
