The clamping connection has the advantages of simple structure and easy assembly, and the tight connection of the switch door 21 and the switch door bracket 22 can be realized through the clamping connection. In addition, the cost can be reduced while the connection strength of the switch door 21 and the switch door bracket 22 is ensured. For example, in some examples of the present invention, one side of the switch door 21 adjacent to the switch door bracket 22 has a plurality of second protrusions, the switch door bracket 22 is provided with a plurality of slots corresponding to one another, and the plurality of second protrusions are respectively engaged with the plurality of slots.

In some embodiments of the present invention, as shown in fig. 5 and 6, the switch door 21 and the switch door bracket 22 are connected by a fastener. The fastening member has the advantages of simple structure and easy assembly, and the tight connection between the switch door 21 and the switch door bracket 22 can be realized through the fastening member. In addition, the cost can be reduced while the connection strength of the switch door 21 and the switch door bracket 22 is ensured. Alternatively, the fastener may be a screw, bolt or stud.

In some embodiments of the present invention, the second air outlet 12 is provided with a non-wind-sensing cover, the non-wind-sensing cover is provided with a plurality of micro holes, the non-wind-sensing cover can open or close the second air outlet 12, and when the air-conditioning indoor unit 100 starts the non-wind-sensing mode, the non-wind-sensing cover closes the second air outlet 12. Therefore, the air flow blown out from the second air outlet 12 can be prevented from directly blowing the user, and the use comfort of the user can be improved.

According to some embodiments of the present invention, the indoor unit of air conditioner 100 further includes: the heat exchanger 6, the heat exchanger 6 is set up in the body 1. For example, in some examples of the present invention, a water pan is disposed at the bottom of the heat exchanger 6 for collecting condensed water and discharging the condensed water, an air inlet 13 is disposed on the casing 1, and the air inlet 13 is disposed opposite to the heat exchanger 6.
