Likewise, the second connector includes a second contact surface, the second contact surface being opposite the volute floor; the volute bottom plate comprises a second matching surface, the second matching surface is opposite to the second connecting piece, and the second matching surface and the second contact surface are provided with surfaces which are mutually attached, so that the second connecting piece is in sealing connection with the volute bottom plate, and therefore, the cold quantity can be prevented from leaking out from the space between the second connecting piece and the volute bottom plate to influence the refrigerating capacity of the indoor unit of the air conditioner.

As shown in fig. 14, in some embodiments, the first air deflector 711 includes: the first portion 7111 and the second portion 7112 are connected to each other, the first portion 7111 and the second air guiding plate 712 are disposed opposite to each other, the second portion 7112 and the third air guiding plate 713 are disposed opposite to each other, and an included angle between an extending direction of the first portion 7111 and an extending direction of the second portion 7112 is an acute angle.

The utility model discloses an extension direction of machine in air conditioning sets up the extending direction of two parts of first aviation baffle into the acute angle, has reduced the air-out angle of air-out subassembly for can realize forward blowing, can prevent again from the wind direct-blowing user that the indoor air outlet is seen off, can realize encircling air supply through the first portion and the second portion that are the angle setting again, satisfy user's user demand, improve user and use and experience.

As shown in fig. 1 and 11, the indoor air outlet 102 includes a first air outlet 1021 and a second air outlet 1022 which are arranged side by side; the first air outlet 1021 corresponds to the fifth air duct 701, and the second air outlet 1022 corresponds to the sixth air duct 702. Due to the acute angle of the first air deflector 711, when the air-conditioning indoor unit is used, the air outlets on the front panel are distributed on two sides when viewed from the front, so that no obvious air outlet exists, and the visual effect is good.

Finally, it should be noted that: the embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments are referred to each other.

The above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
