Problems solved by technology
[0003] However, for other existing vertical air-conditioning indoor units with two cross-flow fans arranged up and down, since bearing seats and air duct separators are arranged between the two cross-flow fans, it is not very convenient. Suitable for the use of the above-mentioned electric auxiliary heating structure
Perhaps it is for this reason that the vertical air conditioner indoor unit with two cross-flow fans arranged up and down in the prior art has never applied an electric auxiliary heating structure, so it does not have a high heating capacity for quickly adjusting the indoor temperature. ability

An upright air conditioner indoor unit, comprising: a housing (10), which is provided at the front side with multiple air outlets (111) and provided at the rear side with an air inlet (121); a heat exchanger (20) provided within the housing (10); at least two crossflow fans (30) that are sequentially arranged in the vertical direction within the housing (10) and are axially collinear; and an auxiliary heater (40) extendedly provided in the vertical direction adjacent to the at least two crossflow fans (30) for auxiliary heating of air driven by the at least two crossflow fans (30) when the upright air conditioner indoor unit is running a heating operation. Every adjacent two crossflow fans (30) are provided therebetween with a bearing base component (50) used for accommodating a fan bearing. The bearing base component (50) is provided with an additional air duct (53) at least on the side opposite the auxiliary heater (40). An additional fan (54) is provided within the additional air duct (53). The additional fan (54) is configured for promoting air to flow into the additional air duct (53), to absorb the heat generated at an area of the auxiliary heater (40) opposite the bearing base component (50), then to flow out of the additional air duct (53) to be blown to the air outlets (111), thus increasing the temperature of the air blown from the air outlets (111) and reducing heat loss.
Description
technical field [0001] The invention relates to an air conditioner, in particular to a vertical air conditioner indoor unit. Background technique [0002] The heat exchanger modules of some existing vertical air conditioner indoor units are provided with an electric auxiliary heating structure, which is used to enhance the heating capacity of the indoor unit, thereby quickly adjusting the indoor temperature. The electric auxiliary heating structure is usually arranged on the front side of the heat exchanger. Due to the limitation of the internal space of the indoor unit, the electric auxiliary heating structure is usually adjacent to the cross-flow fan of the indoor unit. [0003] However, for other existing vertical air-conditioning indoor units with two cross-flow fans arranged up and down, since bearing seats and air duct separators are arranged between the two cross-flow fans, it is not very convenient. It is suitable to use the electric auxiliary heating structure ment...
