Referring to fig. 1 to 6, the floor type air conditioner indoor unit 100 of the present invention includes a casing 110, an air deflector 130 and an air dispersing assembly 160. The casing 110 includes a panel 111 and a rear casing 116 connected to the panel 111, at least one side of the rear casing 116 is provided with a main air outlet 119, the panel 111 is provided with a secondary air outlet 112 close to the main air outlet 119, and a heat exchange air duct (not labeled) communicated with the main air outlet 119 and the secondary air outlet 112 is provided in the casing 110. The air deflector 130 is installed at the main air outlet 119 to open or close the main air outlet 119, and a plurality of air dissipation holes are formed in the air deflector 130 in a penetrating manner; the air diffusing assembly 160 is disposed at a rear side of the secondary outlet 112, and the air diffusing assembly 160 is adapted to allow an air flow to pass therethrough, diffuse the air flow passing therethrough, and blow the air flow out of the secondary outlet 112.

In the embodiment of the present invention, the whole housing 110 extends in the up-down direction, and the cross-sectional shape of the housing 110 may be circular, elliptical, rectangular, or the like, and may be selected according to the actual use requirement, which is not specifically limited. The panel 111 and the rear case 116 may be integrally formed, or may be separately formed, for example, the panel 111 and the rear case 116 may be detachably connected. An air inlet 117 is arranged at the back of the rear shell 116, a main air outlet 119 is arranged at the left side and/or the right side of the rear shell 116, a heat exchange air duct communicating the air inlet 117 with the main air outlet 119 is arranged in the shell 110, a secondary air outlet 112 close to the main air outlet 119 is arranged on the panel 111, and the secondary air outlet 112 is also communicated with the heat exchange air duct, so that the air flow in the heat exchange air duct is divided into two parts, one part flows to the main air outlet 119 and is blown out through the main air outlet 119, the other part flows to the secondary air outlet 112 and is blown out through the secondary air outlet 112. Specifically, the primary air outlet 119 and the secondary air outlet 112 are both elongated air outlets extending in the up-down direction.

The cyclone rotor 163 is installed in the box body 161a and is disposed corresponding to the first through hole 162a and the second through hole 162 b. Of course, the mounting box 161 may be integrally formed, and is not particularly limited.

The operation modes of the floor type air conditioner indoor unit 100 of the present invention include a no-wind-induction mode and a normal cooling and heating mode. Referring to fig. 3 and 4, in the non-wind mode, the switch door 140 slides towards the middle into the accommodating cavity 120, the secondary air outlet 112 is opened, so that the air dispersing component 160 is exposed, the air deflector 130 rotates to close the primary air outlet 119, at this time, the air flow in the heat exchange air duct is divided into two parts, and a part of the air flow is dispersed through the air dispersing holes on the air deflector 130 and blown out from the primary air outlet 119; the other part of the airflow is diffused through the air diffusing assembly 160 and blown out from the secondary air outlet 112, so that the non-wind-sensing air outlet area is effectively increased, the non-wind-sensing air quantity is increased, and the comfort in the non-wind-sensing mode is improved. Referring to fig. 5 and 6, in the normal cooling and heating mode, the switch door 140 slides out of the accommodating cavity 120 to close the secondary air outlet 112, so as to shield the air diffusing assembly 160, the air deflector 130 rotates to open the primary air outlet 119, and at this time, the air flow in the heat exchange air duct flows to the primary air outlet 119 and is blown out through the primary air outlet 119.

The invention also provides an air conditioner, which comprises an outdoor unit and a floor type indoor unit 100, wherein the floor type indoor unit 100 is connected with the outdoor unit through a refrigerant pipe. The specific structure of the floor type air conditioner indoor unit 100 refers to the above embodiments, and since the air conditioner employs all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
